Source: Music of the Avant-Garde – also known and hereafter referred to as Source Magazine – was an independent, not-for-profit musical and artistic magazine published between 1967 and 1973 by teachers and students of the University of California, Davis, California. It emerged from the flourishing Californian musical experimentalism of the late 1950s-early 1960s, at UC-Davis and Mills College. The 11 issues document new music practices of the period like indeterminacy, performance, graphic scores, electronic music and intermedia arts.
