A few weeks back I had the pleasure of speaking with Barry Lederer who was involved in many facets of Disco. Barry began by Djing at several New York area clubs and later taking over Tom Moulton's "Disco Mix" Billboard column and being one of the principals of Graebar Sound. The team at Graebar designed and installed the sound systems for the Saint, 12 West, Trocadero Transfer, Probe and several other world class night clubs in the 1970s.
