This video captures Bill T Miller (BTM) creating an Arp-O-Matic Orgy Of Noise in his Headroom Studios (Boston), back in 2003.
This vintage ARP Odyssey Synthesizer (from 1974) was purchased by Miller in 1976 (used) and is one of the original white face models.
This clip appears on the Orgy Of Noise 2004 DVD.
