During the construction of the new Anthology Film Archives site on 80 Wooster Street, New York, in 1973, Nam June Paik performed a series of the Fluxus Sonata in the venue, beginning with Fluxus Sonata No. 1. The photograph shows a performance of Fluxus Sonata No. 4 in 1975. In front of several turntables, Paik put an LP on one of them and listened carefully with his arms crossed; and then he moved to another turntable to activate another LP. With the two vinyl records rotating simultaneously, he oscillated between the phonographs, interrupting and spinning them with his hands. Physically intervening in the operation of record players, this performance is much like today’s DJing.
