You know about
Igra Staklenih Perli? Are you somewhere from ex-Yugoslavia or you know them through some other ways? I thought they were pretty obscure even in ex-Yu.
About kraut-rock, there is a very good thread in Avant Garde forum -
Kosmiche Musik/Krautrock - with youtube links to a great documentary about German music from that time.
Another great thread -
The 60s Psych Thread in the Prog & Psychedelic Rock forum.
Also there is a shoegaze thread in Indie/Alternative forum -
Shoegaze
Edit: Since you mentioned Psychic TV I take it you like industrial and similar genres -
Ambient, industrial, noise, etc...
Basically there's a lot of talk about trippy music, usually in Avant Garde/Experimental forum and Prog & Psychedelic Rock forum
Hope you enjoy it.
