Photograph. Chris Swansen, a notable jazz performer, was a Moog studio musician who often performed with the very latest Moog equipment. He is pictured here preparing for the legendary live Moog concert at MOMA. The event, which involved customized synthesizers featuring the first "presets," took place in August 1969, just two weeks after Woodstock, and is widely considered to have turned into a "happening." The band Chis Swansen led featured Jon McLaughlin, Hal Galper, and Bobby Moses.
