Glass later stated in his autobiography "Music by Philip Glass" (1987) that the new music performed at Pierre Boulez's "Domaine Musical" concerts in Paris lacked any excitement for him (with the notable exceptions of music by John Cage and Morton Feldman), but he was deeply impressed by new films and theatre performances. His move away from modernist composers such as Boulez and Stockhausen was nuanced, rather than outright rejection: "That generation wanted disciples and as we didn't join up it was taken to mean that we hated the music, which wasn't true. We'd studied them at Juilliard and knew their music. How on earth can you reject Berio? Those early works of Stockhausen are still beautiful. But there was just no point in attempting to do their music better than they did and so we started somewhere else." He encountered revolutionary films of the French New Wave, such as those of Jean-Luc Godard and François Truffaut, which upended the rules set by an older generation of artists, and Glass made friends with American visual artists (the sculptor Richard Serra and his wife Nancy Graves), actors and directors (JoAnne Akalaitis, Ruth Maleczech, David Warrilow, and Lee Breuer, with whom Glass later founded the experimental theatre group Mabou Mines). Together with Akalaitis (they married in 1965), Glass in turn attended performances by theatre groups including Jean-Louis Barrault's Odéon theatre, The Living Theatre and the Berliner Ensemble in 1964 to 1965. These significant encounters resulted in a collaboration with Breuer for which Glass contributed music for a 1965 staging of Samuel Beckett's "Comédie" ("Play", 1963). The resulting piece (written for two soprano saxophones) was directly influenced by the play's open-ended, repetitive and almost musical structure and was the first one of a series of four early pieces in a minimalist, yet still dissonant, idiom. After "Play", Glass also acted in 1966 as music director of a Breuer production of Brecht's "Mother Courage and Her Children", featuring the theatre score by Paul Dessau.
