Very much agreed. David Lee Roth suited Van Halen to a tee. His solo career was a bomb, I didn't like him much then.
Since I can't categorise them, and this includes a few related genres, I think Faith No More deserve a mention. Personally, I think they are one of the most talented bands to grace the music scene. Funniest thing is, none of them liked each other. They were different. Each song was different. They weren't a typical rock band. I think each individual member of that band were geniuses of their own instrument.
They are personally one of my favourite bands, probably my favourite band outside of metal. Anyway, that's my $0.02.
