For $20, Bleep is selling a 55 track “Guide To Electronic Music” compilation starting from Olivier Messiaen and Pierre Shaeffer in the 1930s and 1940s through Daphne Oram, Morton Subotnick, Throbbing Gristle, Afrika Bambaata, Phuture, and Basic Channel, all the way to J Dilla and James Blake. (Of course it’s not comprehensivem, nor does it claim to be.) The project drew out of a Facebook timeline chronicling that same history. “A Guide To Electronic Music” (Thanks, Vann Hall!)
