Porcupine Tree

PT is one of the best bands around period. I'd go with stupid dream, lightbulb sun, or in absentia.

Steve is a twisted man but a pure genius.

What's the difference between eccentric and crazy? One is successful and the other is not.
 
Blackfield is really good too if you need something even lighter to listen to.
 
now if only that Wilson/Akerfeldt/Portnoy project would happen...

imagine the field day the opeth board will have with THAT one
 
An interesting concept. It's well trodden, but the central themes hold plenty of merit. Nevermore have wrote about this sort of thing before, too.
