Would LOVE to see but WON'T
Miles Davis- Jack Johnson!!!! For all of you unknowing 'basers- if you have never heard Jack Johnson or Bitches Brew by Miles Davis, then you really have NO CLUE ABOUT PSYCHEDELIC MUSIC!! Do yer'self a HUGE FUCKING FAVOR and check these out. That said, this is probably too complex for Phish (Hah! I Said IT!)
Sailing the Seas of Cheese- how epic would that be? That said, Gordo probably couldn't pull that off either... (Hah again!)
Any Zappa would be unreal
Violent Femmes would be fun for us old folks (I'm 30)
I think its more likely to be Meddle, Pet Sounds (this has been discussed since the phirst phish cover), Ween, or maybe the Doors for the great sing-along-ability of all the tunes, its a SUPER psychedelic album, plus the LA connection.
IF it is TEN or Nevermind, I will OFFICIALLY never listen to Phish again. They are on warning from when they had Kid Rock come out in Vegas in 2000, & I simply will not put up with that shit.
The way to make them play Pearl Jam or Nirvana would be for EVERYONE in the crowd's costume to be a flannel shirt & blue jeans (but NO freddy mask)
