Zoogz Rift. Just... Zoogz Rift.
Imagine someone like Frank Zappa, with heavy jazz influences, bizarre jam sessions, lots of instruments not customary to rock, i.e. marimbas (guy loves marimbas), saxophones, brass sections, usually surreal or comedic lyrics. The main difference is that he doesn't really sing as much as rant angrily in some songs. Definitely not for everyone, but it works for me. If you're into avant-garde music, give Zoogz Rift a shot. You won't be disappointed.
