Srangest ,most out there sounding music

For a true original try Harry Partch. An American composer who developed his own microtonal musical scale in the 30s and wrote for it until his death in the early 70s. His compositions often combined theater along with his striking and unusual instruments (which he invented to play his 40+ note scale). His 3 LP release "Delusion and the Fury" had one record showcasing his instruments along with a great booklet containing many pictures of them.
