Thanks for the tips, all. Just got back from my SF travels and managed to visit Aquarius (Mission St.), Amoeba (Haight), and Rasputin's (Haight). Amoeba was the jackpot store of the bunch, having extensive electronic, experimental, and new age sections to explore (in addition to the standard fare). Rasputin's was worthless.
Picked up some nice bargains that I'm looking forward to digesting this week:
Sylvain Chauveau - The Black Book of Capitalism (Type)
Maps and Diagrams - Get Lost (Time Released Sound; non-deluxe edition)
Stray Ghost - Those Who Know Darkness See The Light (Time Released Sound; non-deluxe edition)
Pleq/Spheruleus - Quietus Gradualis (Time Released Sound; non-deluxe edition)
Deepchord presents Echospace - The Coldest Season (Modern Love; gave away my old copy)
Ingenting Kollektiva - Lost Beyond Telling (Invisible Birds)
I'll prob post a line or two about these in "now playing" as I digest them.
