Good old AC/DC. Across four decades, two singers, and hundreds of songs, the band’s sound has remained remarkably consistent — why fix what’s not broken? There’s something comforting about picking a tune from just about anywhere in a band’s history and knowing it will share the same beloved building blocks as almost any of its other songs.
However, retreading the same formula simply won’t do for the world’s more restless music makers. Whether it’s losing (or gaining) a member of the band, discovering new musical technology, delving into commercial prospects, or just getting bored with repetition, there’s a certain class of musicians unafraid to tear down their established style for a brave new sound. To celebrate these fearless innovators, here are some of the most iconic bands in music history that drastically switched up their sound — for better or for worse!
The Beatles
We might as well start at the beginning. The Beatles may not have been the first group of musicians to break the shackles of the traditional rock ‘n’ roll formula, but the band inarguably set the precedent for constant sonic reinvention in the realm of rock music.
For many fans of John, Paul, George, and Ringo’s later works, the first few Beatles albums can appear a bit quaint. But make no mistake — the songwriting of albums like Please Please Me and With the Beatles is head and shoulders above their peers. However, that music still dwells well within the confines of typical late ’50s/early ’60s rock ‘n’ roll. Cracks began to show by the time A Hard Day’s Night and the Bob Dylan–influenced Beatles for Sale rolled around. And Help! positively solidified the sound of the pre-psychedelic ’60s. Still, if the Beatles had called it quits here, then they likely would have been remembered more for their immaculate songcraft than for their innovation.
Then came the one-two punch of Rubber Soul and Revolver. Beatles fans largely regard these two albums as the beginning of the band’s maturation, rending the sunshine-pop sheen of the early ’60s into the smoky stages of psychedelia. Sitars, string octets, distorted guitars, reversed guitars, songs with no guitars, and some of the world’s first instances of the recording studio being utilized as an instrument unto itself . . . Only three years after their first proper LP, the Beatles left the sound that made them worldwide stars in the dust.
Yet, that was only the beginning. Everything that can possibly be said about the monumental influence of 1967’s Sgt. Pepper’s Lonely Hearts Club Band has already been said a million times over, so I’ll simply say that critics constantly rate it as the most influential rock album of all time. This is a rather funny classification because most of the album really isn’t rock at all.
Sgt. Pepper’s represented a further descent into Indian-influenced sounds, psychedelic rock, so-called “granny music” (John Lennon’s term, not mine!), electronic sounds, and a complete irreverence for musical boundaries that would last up until the band’s breakup in 1970. In about a decade, the Beatles reinvented their sound several times over, forged the musical landscape of popular music, and forever set the standard for all genre-bending rock musicians that would come after.
Bob Dylan
Almost any musician who has been in the game as long as Bob Dylan is bound to make at least a few shake-ups. Over the course of half a century and nearly 40 studio albums, Dylan has explored rock, gospel, blues, jazz, and countless other sounds. But his transition from strictly acoustic folk to electric guitar–equipped rock was one of the most divisive stylistic swaps in music history.
To modern listeners, this change is, well, not that impressive. He switched from acoustic guitar to electric guitar — big deal, right? Plenty of musicians do that all the time. Plus, it’s not like electric instrumentation was a recent invention — by the time Dylan put out his first album in 1962, the electric guitar was nearly as old as he was. Despite this, his first four albums were comprised of songs that rarely strayed from the folk singer/songwriter tradition of a steel-string guitar, harmonica, vocals, and a stern disillusionment with the modern world.
So, when Dylan embraced that same modern world’s terrifying 6-string electric monstrosity onstage during his performance at the 1965 Newport Folk Festival, the folkies recoiled in betrayal. Most fans were likely expecting Dylan, an acoustic guitar, and nothing more. Instead, they got the Paul Butterfield Blues Band. The reception was mixed, resulting in a chorus of boos from the die-hard, anti-electric folk fanatics. It’s often said that Dylan “electrified one half of the audience and electrocuted the other.”
Dylan is famous for his somewhat prickly attitude, so this response likely only reinforced his switch toward an electric sound. A good thing, too, since it resulted in some of the greatest albums in rock history, including Highway 61 Revisited, Bringing It All Back Home, and Blonde on Blonde. While much of Dylan’s early traction was gained during his previous acoustic performances at the Newport Folk Festival, his electric incident resulted in a nearly four-decade hiatus from the event. He returned in 2002 — only he cleverly disguised himself in a wig and fake beard to fool the folkies that had so spurned him back in 1965.
Bee Gees
Long before the three Gibb brothers were disco gods, Bee Gees spent its early days crafting sophisticated ’60s pop and garnering comparisons to the Beatles and the Beach Boys.
For nearly a decade, Bee Gees spent its creative energy exploring the reaches of soft rock, folk rock, and psychedelia, much of which is held in high critical regard. Any fan of standard ’60s baroque-pop masterpieces from bands like the Zombies and the Beach Boys will surely find much to love in an album like 1969’s Odessa. The band experienced quite a bit of interpersonal drama, musical ruts, and breakups during the following period, but they eventually re-formed and made a rather unexpected turn.
The sounds got funkier, the R&B influence became a driving force, and Barry Gibb’s voice defied human biology by becoming even higher with age, reaching up into the farthest frequencies of falsetto territory. Disco had arrived in the mainstream. This would prove to be the most important musical choice the Bee Gees ever made, as it took them from being a reasonably successful rock band to one of the greatest-selling artists of all time, rivaling the likes of Elvis Presley, Michael Jackson, and the Beatles.
Talk Talk
Switching from standard rock instrumentation to synths was a typical move back in the late ’60s, ’70s, and ’80s. After all, the technology was brand-new, and how could a musician possibly know that they were destined for the synthesizer before it was even invented? London-based group Talk Talk was one of the few famous bands to make the oppositemove.
From 1982 to 1988, Talk Talk was firmly rooted in the ’80s synth-pop tradition. Any student of the era is surely familiar with the exuberant, effect-laden anthem, “It’s My Life,” a sound that they refined across their first three studio albums. It’s top-tier synth-pop, but there was little indication that they would ever stray from that sound.
One can only imagine hearing what front man Mark Hollis proclaimed after the band recorded their third album, The Colour of Spring: “Pack up the synthesizers, boys: it’s time to invent post-rock.” Alright, maybe founding a new genre wasn’t at the forefront of their minds. But Talk Talk’s breakneck transition from synth-pop to the ethereal rock/jazz/classical hybrid they explored on their last two albums was without precedent entirely. Absolutely nothing on their first three records gave even the slightest hint of what was to come. Most artists dip their toes into the water before making a big change. Talk Talk, on the other hand, dove in headfirst.
1988’s Spirit of Eden and 1991’s Laughing Stock were assembled via hundreds of hours of studio recordings, both intricately and immaculately arranged with nary a synthesizer to be found. Instead, the band gravitated toward more organic, natural instrumentation, including pianos, strings, electric guitars, beautiful jazz-influenced percussion, and experimental digital audio treatment.
Songs were stretched out into the upper reaches of the five-minute mark and often into double digits. It’s no surprise that these two albums have been retroactively categorized into the genre of first-wave post-rock. The long, non-traditional song structures, jazz/classical influences, and extended instrumental sections almost certainly influenced later post-rock stalwarts, such as Bark Psychosis, Chicago’s Tortoise, and the genre’s poster-child band, Godspeed You! Black Emperor.
Ronnie James Dio
Ronnie James Dio is a monumental metal vocalist whose influence can only be matched by the inimitable Ozzy Osbourne (whom Dio coincidentally replaced in Black Sabbath when Osbourne left the band in 1979). But Dio wasn’t always the devil-horn-bearing icon we celebrate today.
By the time heavy metal had truly found its footing in the early ’70s, Dio was nearly 30. He kicked off his music career all the way back in 1957. So, what did the front man of Dio, Rainbow, and Black Sabbath do before heeding the call of heavy metal?
Yup. The man who would later be accused of satanic worship for his frightening stage antics originally played a far more menacing role — a doo-wop ’60s pop heartthrob. This era is more or less a curiosity for most fans of Dio’s later work, but it’s just about the most dramatic stylistic shift in the history of metal.
Fleetwood Mac
Many of the artists on this list have fans that appreciate the entire spectrum of their output, no matter how far they strayed from their original sound. Fleetwood Mac isn’t one of these bands.
Formed in 1967 by Peter Green after he left John Mayall & the Bluesbreakers, Fleetwood Mac started life as a hard-edged British blues band. This was much in the same vein as Green’s previous occupation — he had replaced Eric Clapton when Clapton departed from John Mayall’s group, and Green is by all accounts right up there with Clapton in the pantheon of legendary British blues guitarists. Along with Mick Fleetwood and John McVie, the band’s first few albums are renowned as some of the period’s finest blues-rock works. It’s fair to say that many fans consider Green’s dynamic, melodic, and innovative guitar stylings as the band’s defining voice.
Then, just like Pink Floyd’s Syd Barrett, Green became a mental casualty of the era’s all-too-common psychedelic drugs. He left the band in 1970, spending many years outside of the music industry entirely to mentally recover. While Green would eventually come back as an uncredited contributor to a few of the band’s later songs, Fleetwood Mac had arguably lost the soul of its blues-rock beginnings.
The years that followed were tumultuous and full of lawsuits. The band lost members to cults (seriously) and had undergone enough personnel changes that they sometimes performed under the name “The New Fleetwood Mac.” But the biggest change came in 1975 when two new members joined the band: Lindsey Buckingham and Stevie Nicks.
This version of the band was by far Fleetwood Mac’s most famous and commercially successful iteration — there are surely millions of fans of “Dreams” or “Go Your Own Way” that have not an inkling that the band was originally a raunchy blues-rock outfit. Fleetwood Mac would continue its path toward pop dominance with all-time classic albums, such as Rumours, but never returned to its bluesy roots.
It’s almost a bit disingenuous to imply that the earlier Peter Green–led band was the same as its later pop-superstardom band, but that’s their call, not ours! To be fair, some of the original founders — drummer Mick Fleetwood, bassist John McVie, and keyboardist Christine McVie — form the band’s name (Fleetwood and McVie). So, the band is still the original Fleetwood Mac in title, if not in sound. Both sides of the coin have their fair share of ardent fans ready to argue about which era is superior. But the band’s transformation from blues virtuosity to slick studio pop is certainly one of the most drastic in music history.
Miles Davis
Who was the most innovative horn player of the ’50s? Likely Miles Davis. What about the ’60s? Miles Davis. ’70s?
. . . Do you really need to ask?
From backing Charlie Parker in the ’40s to forming the foundation of hard bop to the invention of modal jazz to his later jazz-fusion experiments, it’s impossible to overstate Miles Davis’s towering influence on the 20th century’s musical legacy. Several books could be written on Davis’s shape-shifting stylistic nature — and he had numerous all-time classic albums to prove it.
Davis spent the ’50s sharpening his bebop chops, exploring the reaches of cool jazz, and (most importantly) elevating jazz to an entirely new level of sophistication and emotion with the modal moods of 1959’s Kind of Blue. This album was frequently referred to by critics as one, if not the crowning musical achievement of the 20th century.
That’s all well and good, but not a year later, Davis had shifted gears completely — he opted for the Iberian flair of Sketches of Spain. This album bridged the gap between classical music, traditional Spanish music, and American jazz, resulting in a breathtakingly beautiful third-stream suite of songs that was far closer to a symphony than a standard jazz album.
Ever restless, Davis continued experimenting with the very framework of jazz throughout the ’60s. At the same time, rock music’s psychedelic and progressive revolution represented the maturation of its genre into a sound that could rival the complexity of jazz. So, why not combine the two?
Check out these tracks from two of Davis’s classic, late ’60s albums, Nefertiti and In a Silent Way:
These two records came out one year apart from each other. Davis had been bitten by the jazz-fusion bug and would spend much of the ’70s breaching strange and stranger musical ground until he faced an early (but temporary) retirement due to health issues.
It’s impossible to overstate just how fearless Miles Davis was when it came to dramatic stylistic shifts. It’s true that jazz is generally more fluid and resistant to hard boundaries when compared to other types of music; however, the staggering breadth of Davis’s musical output simply dwarfs just about any other musician from the 21st century, regardless of genre.
Davis’s ensembles weren’t exactly hurting in the talent department either; many of his most iconic albums featured the likes of John Coltrane, Cannonball Adderley, John McLaughlin, Herbie Hancock, Chick Corea, and perhaps the most idiosyncratic jazz pianist in history, Bill Evans. Frankly, you’d have to try to remain musically stagnant when playing with musicians of such lofty calibers!
Pantera
Two decades after the tragic passing of virtuoso guitarist Dimebag Darrel in 2004, Pantera’s Cowboys from Hell and Vulgar Display of Power albums are still celebrated by metal fans as two of the genre’s crowning achievements. But what many fans might not know is that the band’s first three releases were spent glamming it up before they perfected their signature groove-metal grind.
The band has effectively disowned this period of their career, often referring to Cowboys from Hell as their true debut album. You can’t even find their earlier releases on most streaming platforms — a fact that likely bothers only the most hard-core of Pantera fans, as the band’s early works are not regarded nearly as well as its later masterpieces. Still, Pantera’s hard shift from glam to groove metal is an exceptionally interesting transformation; it shows us that even the most gifted of musicians sometimes have trouble finding their footing.
Radiohead
Radiohead is another one of those bands where you can split their fanbase straight down the middle. Do you like loud, angry guitar music? Perfect — check out their first three albums. Do you like synths, electronic experimentation, and less angry guitar music? Perfect — listen to Kid A and beyond. That’s a massive oversimplification, but listeners will almost certainly prefer either the band’s early post-grunge, Brit-rock sounds or their 21st-century electronic experimentation.
Ah, “Creep.” It’s far and away Radiohead’s most popular song — it has nearly four times as many plays as any of the band’s other tracks on Spotify. But most “hard-core” Radiohead fans treat it as an embarrassment at worst and a necessary evil at best, providing the band with enough commercial success to fund their esoteric aspirations.
1993’s Pablo Honey, the album on which the song is found, is a well-crafted alternative offering that anyone with a propensity for ’90s grunge will enjoy. Their sophomore album, The Bends, doesn’t topple any musical barriers, but it does represent Thom Yorke and company truly coming into their own as songwriters.
Their next album, OK Computer, bridges the gap between the band’s two fan bases; almost every Radiohead fanatic considers this one of the band’s brightest moments. Songs like “Paranoid Android” and “Karma Police” mark a serious upward shift in musical and lyrical maturity, but they still rock. There are still guitar solos.
Well, that was all about to change. Imagine the average Radiohead fan’s shock back in 2000 when they popped the Kid A CD into their Walkman and expected another helping of moody alt-rock only to be greeted instead by not one but two opening tracks without a single guitar!
Kid A didn’t simply modify Radiohead’s alt-rock/Brit-rock formula with a couple of synthesizers and drum machines; it completely obliterated their old sound. Several of the tracks are more akin to Thom Yorke’s self-admitted electronic music hero Aphex Twin than anything else the band had previously released. The rest can still be called “rock,” but it’s a far weirder, gloomier kind of rock. It’s rock, but it doesn’t want to rock anymore.
Unfortunately for fans of the band’s first three albums, this wasn’t a one-time deal. 2001’s Amnesiac is possibly the band’s most out-there offering, and 2003’s Hail to the Thief wasn’t at all interested in bringing back Johnny Greenwood’s ripping OK Computer-era guitar work. Radiohead’s affinity for the strange has only grown stronger since then. And while fans can be divided, both of Radiohead’s eras are endlessly rewarding for those with an open musical mind.
Ice-T
A rapper, an actor, an author, and a producer. Ice-T has worn many hats during his four-plus decade career. While most fans would recognize him primarily for his pioneering work in defining the sound of gangsta rap in the late 20th century, his musical output has long been split between his hip-hop works and his thrash/hard-core/metal/rap band, Body Count.
Frankly, it’s tough even to call the band a side project, considering Body Count now has nearly as many albums as Ice-T’s rap career. Moreover, he hasn’t released a straight rap studio album since 2006. However, Body Count has been going steady since 1992, releasing their latest album, Carnivore, in 2020.
