This double-CD set combines two of the key titles of Columbia Records’s legendary “Music of Our Time” series curated by David Behrman. Jeanne Kirstein’s recording of Cage’s early keyboard works remains a touchstone of Cagean interpretation notwithstanding the passage of time.

Christian Wolff recalls, "I remember Cage saying that Jeanne Kirstein’s playing caught the spirit in which the pieces were written at the time he wrote them—a kind of simple excitement and enthusiasm (also, surely, out of the discovery of the preparing of the piano and the great new sounds)."
