Forbidden Planet
This is a weird album. It is considered to be one of, if the the first record comprised entirely of electronic sounds and instrumentation (mostly oscillators and echo loops). I found out about it years ago while reading the RE/Search book Incredibly Strange Music. The “music” consists only of various electronic bleeps and bloops with no attempt at song structure, melody or anything even remotely musical. Despite this, it makes a good CD to play in the background if you just want atmosphere. It will often go into rotation for me around Halloween.
