Steve Reich: Piano phase rehearsal with a caretaker joining in with the beat

Steve Reich: Piano Phase performed by Anna Buchenhorst and Lars Fredén in Gusta Vasa church, Stockholm, Sweden.
Piano Phase is minimalist composition by American composer Steve Reich, written in 1967 for two pianos (or piano and tape). It is one of his first attempts at applying his "phasing" technique, which he had previously used in the tape pieces It's Gonna Rain (1965) and Come Out (1966), to live performance.
