This expansive documentary tracks the evolution of electronic music, one of the artistic revolutions of this century. Modulations is truly encylopedic, but moreover, it is entertaining. Using high-end graphics, provocative interviews with legendary and current figures, and a pulsating stream of the music, Lee takes us from a rave on Mt.Fuji to world clubs playing this constantly morphing art form: house, acid, ambient, euro-disco, electro-rap. The turntable is a musical instrument, dj′ing is an interpretive act of making music, and the revolution continues beyond avant-grade greats Cage and Stockhausen. Indeed, electronic music is where human and machine are fused in perfect harmony. (Im Hyun-Ock)
