The journal Source: Music of the Avant-garde was and remains a seminal source for materials on the heyday of experimental music and arts. Conceived in 1966 and published to 1973, it included some of the most important composers and artists of the time: John Cage, Harry Partch, David Tudor, Morton Feldman, Robert Ashley, Pauline Oliveros, Dick Higgins, Nam June Paik, Steve Reich, and many others. A pathbreaking publication, Source documented crucial changes in performance practice and live electronics, computer music, notation and event scores, theater and installations, intermedia and technology, politics and the social roles of composers and performers, and innovations in the sound of music.
