Bands where at least one member seems resolutely in a different band / genre

I was looking for metal bands with explicitly jazz drummers where not only did the drummer stick to jazz playing style and idiom but everyone else remained firmly in metal without being a fusion (not being versed in metal or jazz, I failed to find any that weren't "jazzy" metal or "metally" jazz and apparently there is a "jazz metal" genre that isn't quite it), but got to thinking what bands have this dynamic in general, and could only come up with Cheap Trick where half the band are nerds and half the band are heartthrobs, but that's more on the aesthetics/persona side.

Surely sometimes this should happen by accident to long-running bands with lots of lineup changes? I figure at some point Gwar would have had a folk-singer bassist who refused to wear a costume or something like that.

i was watching the streaming coverage of wacken open air a few weeks back and umbra conscientia seemed to be giving it everything on the corpse paint & contact lenses front apart from the rhythm (?) guitarist who seemed to be smirking at the ridiculousness of it all in his hoodie at the back

i don't know if this counts but bill bruford did a lot of gigging work and he nearly always sounded like bill bruford (except '80s king crimson)

which is fine when he was playing for genesis, when he was playing for gong, though, it was kinda weird

also adrian belew being the only member of the remain in light band not doing bumps

hah I was thinking about Belew in Zappa's band for a similar but different reason

Soul Coughing is a pretty funny example of this, Mike Doughty was the one who didn't seem to get what the band was doing, I can definitely remember people wondering why his solo albums sounded like Dave Matthews

if you wanna talk prog...Gordon Haskell in King Crimson. hated the music from the jump and apparently wasn't shy in saying so. turns in a vocal performance which some might describe as sarcastic. he has a solo album and he CAN sing, just not like *that*

The "How Wonderful You Are" guy, yes I was surprised he was ex-KC when that came out.

I suppose Dan Hartnell of the Edgar Winter band would count. "Instant Replay" and "Relight my fire", although I believe his first solo album was more blues-rock based...

Dan Hartman, not Hartnell...

It does seem like it’s mostly the drummer, Gary Young in Pavement comes to mind.

The original post makes me think of Alban "Snoopy" Pfisterer playing a Bach harpsichord piece as an unrelated introduction to the R&B jam of Love's "Revelation". Also, Andy Haas, the saxophonist of Martha and the Muffins, wanted to play free jazz and eventually did, and tried to fit as much of that into their New Wave sound as he could.

the particular metal with jazz drums idea in the op is really funny but i think there's probably a reason no one's done it for real

Roddy Bottum in Faith No More seemed to want to be a new wave/indie band, which is proven out by everything else he did

Papa John Creach seemed way out of place in Jefferson Starship, which was probably for the better.

Roger Daltrey of the Who strikes me as someone who would rather have been in a hard rock band like Led Zep

xpost he was in trouble deep

bill ward is basically playing jazz on the first sabbath album

Dave Mattacks was a jazz drummer before he joined Fairport Convention.

Michael Karoli was the odd man out in Can because he was the only one with any of experience of playing rock music and was about 10 years younger than everyone else.

David Lee Roth?

I also thought for sure this would be an example

but it turns out the rest of the band is fully on board

I wonder if there's a Baby Metal situation where there is full sonic and aesthetic separation between the idols and the corpse grinders.
