CD version. Multi-channel electronic works in Surround Sound. Morton Subotnick was a phenomenon in the late '60s, the first composer to write substantial works for synthesizer that had a wide audience. He has been mentor to generations of composers, and his influence is so pervasive that it would be impossible to trace completely - the electronica movement, for one, reveres him. This release brings together two of his classic analog electronic works, Sidewinder and Until Spring, which were previously only available on LP.

The DVD includes additional video: Subotnick and Tony Martin in conversation about their histories and collaborations (about 60 minutes); Subotnick speaks about his childhood through early years of composing (about 30 minutes); a documentary showing Tony Martin's process to create the liquid light show for Sidewinder.
