If you can get past the irritating opening, this is a fantastic interview with Morton Subotnick on the early days of electronic music at the San Francisco Tape Music Center, the design of the earliest sequencers and the Buchla Music Easel, and his amazement at living in the (technical) future he envisioned in his earliest days. If I have half the creativity and energy as Subotnick does in this video when I reach his age, I will consider myself a very, very lucky man.
