R Kelly went from Rythm and Blues to Prison Blues -u/sleepingweasal

The band Chumbawumba, responsible for the song Tubthumping (I get knocked down, but I get up again,) actually had a thirty year career and they were all over the place.

They started out as a straight up anarcho-punk band. Then they made an album that was entirely acapella protest songs. Then they made folk albums, pop, one with central American sort of flair. -u/helpmelearn12

It feels like cheating to mention David Bowie, but he started out doing English music hall stuff in the style of Anthony Newley and folk rock.

Before moving on to psychedelia, glam rock, electronic music, neo-soul, trad rock, industrial, and a string of albums at the end of his career that can only be described as David Bowie music. -u/drinkthecoffeeblack

Ween (the duo responsible for the hit song "Ocean Man" most notably referred to in the SpongeBob Movie) hasn't had a single album sound the same. Idk if you can dub them any sort of genre.

They started off as I guess what would be considered like a garage/surf/punk rock? But not even? I don't even know...

Then they had an entire country album with banjos and acoustic guitars. The Mollusk is an underwater-inspired, psychedelic, joy ride that is genuinely the most underrated concept album from the 1990's. -u/ahtaylor13
