ABSTRACT
By the 1960s, with the availability of smaller synthesizer components, transistorized circuits, and a thriving industry of rock and jazz gear, many musicians began to experiment with electronic music while performing. The work of several largely improvisational music groups exemplified a small but growing wave of touring electronic musicians in the late 1960s and 1970s. The electronics used by these groups ranged from early transportable synthesizers made by Experimental Music Studio and Bop Moog to effects boxes, and their techniques included feedback and distortion, among others which are now common to rock performances. The music of Musica Elettronica Viva was free-form and radical in the most liberal tradition of John Cage and David Tudor. Instrumentation varied widely, from the simple amplification of room noise and outside sounds to the inclusion of electronic instruments such as the Moog synthesizer and traditional jazz and rock instruments.
