Recommend me some Psychedelic Rock!

[Iota]

Looks like we're talking about prog now.

So, since everthing seems to be allowed:

Captain Beefheart & His Magic Band
Mahavishnu Orchestra
Frank Zappa
Sun City Girls - there's nothing more psychedelic than these guys
Sunburned Hand of the Man
No-Neck Blues Band
Jackie-O Motherfucker
Master Musicians of Bukkake - awesome supergroup; my album of the year so far

Sorry double post lulz

EDIT: just came up with more

Third Ear Band
Hapshash & The Coloured Coat
Vibracathedral Orchestra
