Stephen Drury + Collide-O-Scope Music

The pianist Stephen Drury, who has a soft spot for 20th-century experimental music, brings his highly original vision to John Cage's indeterminate Etudes Australes on the first half of this heady program. The second part belongs to local contemporary-music collective Collide-O-Scope, who will home in on a particularly volatile time for music, 1965 to 1969, performing music by Riley, Glass and Stockhausen.
