Ideofunk beat me to the punch (good form!). Shpongle's album Tales of the Inexpressible is a wild ride. Simon Posford, founder of Hallucinogen and Sphongle, has a band called Younger Brother that continues a similar psy-trance vibe but with a higher degree of live instrumentation, I highly recommend them.
His (Posford's) record label is called Twisted Records (
Twisted Music). Lots of heady music.
Cheers
