Cage: Sonatas and Interludes + Music for Piano

A battery of 85 separate works, most of which can be performed sequentially or simultaneously, with or without overlapping or silence between pieces. That's John Cage's Music for Piano, a sprawling collection that is performed here tonight in its entirety for the first time, 50 years after its completion. It's paired with Cage's equally monumental Sonatas and Interludes, written a few years previously. Both are milestones in his evolution as a composer.
