Houston, we have a problem....
this is not the first poll question
that has been perfectly clear and obvious to YOU
but not that clear and obvious to others.
Any band can have an "orchestra sound"....
but not many of them "have lots of instruments"
any SOLO performer or BAND can "have lots of instruments" on a recording, but that doesn't mean that anyone in the band actually PLAYS them...
they could be session players
with that being said....
the only band I can think of that hasn't been mentioned is Dave Matthews.
they have an orchestra sound, lots of different instruments, which are all played by someone in the band.
now if you're gonna argue that DMB is NOT a classic rock band...
I'm gonna have to hurt ya!
