Serj Tankian has been all over the place! Since System of a Down disbanded (essentially), he's done a couple rock albums, a classical album, a jazz album, has written a few movie scores, even featured in a Tech N9ne song. He's done it all relatively well too! Guy's super impressive and a big inspiration to me musically.

...Remember Snoop Lion?

Taylor swift went from super country in "Our Song" to super pop in things like "Blank Space", " Call It What You Want", and "End Game"

David Bowie. The man has had a handful of completely different musical careers, essentially.

Childish Gambino had his Prince phase

King Gizzard and the Lizard Wizard have been changing their sound constantly since they began as a a band, to the point where this variety is one of the defining attributes of the band.

First album they released was garage/surf rock. To prevent being typecast as a garage rock band their next album was a narrated, spaghetti-western style story album. Since then, they have done psychedelic and progressive rock, thrash metal, acoustic folk, synthpop/dream pop, jazz fusion, microtonal/Turkish rock, two Beastie Boys style tracks, sludge/doom metal, boogie rock, krautrock, and more.

Once you've explored enough of their music and get a sense of their sound you start to notice common styles and characteristics, but it can still be hard sometimes to believe their entire discography is one band.

Anyone ever listen to the Bee Gees earlier stuff, before the disco days? https://m.youtube.com/watch?v=0QTQdAKUZmA

Dir En Grey started as J Pop, then one day appeared on a talk show and were from then on Gothic Death Metal.

Bring Me The Horizon went from deathcore in their early career to bubblegum pop.

Katy Perry was a riot-grrl indie-rocker before she became a pop diva.

Ulver started as a Norwegian black metal band with folk and acoustic influences and starting from the fourth album they've been a high-qualiry electronic music project

The Beatles changed in the very short amount of time they existed. They put out about ten albums in 7 or 8 years and comparing the first with the last they’re almost unrecognizable. Listening with modern ears it’s clear they’re all The Beatles but that’s mostly because of the ubiquitousness of their music.

for some reason my comment showed up in another post so I had to delete it.

deadmau5 didn’t quite do a change of genre but he sort of just adapted with the times to the point that his older music is kind of unrecognizable. His first album “Get Scraped” is much closer in tone to “big beat” and would definitely fit if it were made by artists like The Prodigy or the Qemists, but even then has a few songs that are fairly instrumental and you would likely hear more of on "Where's the Beat" and "There's the Beat" like "Careless," "I Forget," and "Waking Up From the American Dream." He pretty quickly switched styles to sort of dark, deep House and Techno with “Random Album Title”. Nowadays he sort of plays a mix of both, and even his modern songs like “Pomegranate” sound closer to a pop song and probably would’ve got him thrown out of the underground scene 10 years ago

Elvis Costello has taken so many radical departures from his musical style that that’s kind of his musical style.

Born and raised in British Pub Rock, Costello’s Almost Blue album turned country… or perhaps more accurately, in the words of a songwriter he covers on this album… “Cosmic American Music.” I have always admired this Brit’s admiration for, and understanding of, what American Music means, as a genre.

He did an album of old school pop with Burt Bacharach.

He did an album of chamber music with the Brodsky Quartet.

He did an album of… it’s not exactly jazz, in all honesty I say it’s just more cosmic American music… with Allen Toussaint.

He did Marian McPartland’s Piano Jazz.

The guy digs all kinds music, and lets it show.

Going way back, The Bee Gees were a folk band before they dominated disco.

my chemical romance and panic at the disco. their hayday was their first, like, two albums and then they did something completely different. i hate it so much :c

also stars. they used to be my favorite band ever and then went in a completely different direction with the north album. also a very sucky change that dropped them from my favorite band.

Gg allin went from screaming to country. He also had a split album with tiny tim.

Linkin Park went from nu metal to alternative, pop rock etc (I'm not really sure).

thrice went from like pop punk to whatever the fuck the alchemy index was to beggars. they're not really changing it up much these days but they were all over the place for a bit

The band Sparks changed every 7 years or so for almost the past 50 years

Beck? He also had his Prince phase.
