General Idea AIDS BookIf you’re looking for cheap but hip collectibles to decorate your walls and your sound space, these are the sites for you. Steven Leiber Basement has everything from Dada mail art to General Idea multiples to posters and catalogs for Sol LeWitt and Joseph Beuys shows. They have a huge catalog, and a lot of it is relatively cheap. Mutant Sounds has rips of some incredibly rare records and tapes that are pretty much impossible to find in their original formats. Psychedelic, prog, krautrock, free improv, it’s all here. You probably won’t know what most of the stuff is (unless you’re a total music geek), but that makes it all the more fun to explore.
