Larry Fast (Lawrence R. Fast) is a synthesizer expert and composer. He is best known for Synergy, his 1975-1987 series of synthesizer music albums, and for his contribution to a number of popular music acts, including Peter Gabriel's.

Fast grew up in West Essex, New Jersey and attended Lafayette College in Pennsylvania, where he obtained a degree in History. There he took his previous training in piano and violin and melded them with computer science to become interested in synthesized music and to build his own primitive sound-making electronic devices.
