In a Psych/Garage vibe, for me it's gotta be The Scientists 'Wierd Love'. It's truly full on in a 'Fuzzed up' garage vibe, though hard to find nowerdays (it's on some defunct Aussie label called Karbon). Though psych in a trippy sense, some of the best planetary trip ins i've had have been to Ozric Tentacles (Hey!no laughing atthe back there!!)
