Oysterhead...supergroup...hm...well, in my opinion, no. I've heard them and i say they are just a good group. Phish was great because they somehow filled ( most of it at least ) the space, something not done since the grateful dead ( in my opinion). since the grateful dead had 2 guitarists, 2 drummers, keyboardist, bassist, and one time a backup vocalist, its a very incredible feat that phish was able to accomplish with just 4 members. but down to 3, stewy copeland...police drummer, very good. trey anastasio- phish, excellent excellent excellent. les claypool- very good, absolutely dominates that bass. Maybe im asking too much ( sorry major oysterhead phans ) but is for like a trumpet player or a keyboard player, ya know? i mean i absolutely love trey anastasio band. totally.
