University of California Press has put out a beautiful book containing all eleven issues of the legendary new-music magazine Source. Larry Austin edited the journal from the campus of University of California, Davis, between 1967 and 1973, eliciting crucial documents of the musical thinking of Cage, Feldman (his brilliant "Conversations without Stravinsky"), Robert Ashley, Pauline Oliveros, Alvin Lucier, Frederic Rzewski, the young Steve Reich ("Music as a Gradual Process"), and many other luminaries of the late-twentieth-century American avant-garde. Even Stockhausen puts in an appearance, in dialogue with Ashley and Austin. Douglas Kahn edited the book with Austin. A perfect holiday gift for that nephew who can't stop listening to I am sitting in a room.
