Encounters with Conlon Nancarrow, by J rgen Hocker, is the first extensive biography of the American-Mexican composer whose works for the player piano exhibit an innovation and complexity which remains unmatched. Hocker gives insight to the life and personality of the often reclusive Nancarrow, making use of many as-yet-unpublished sources and interviews as well as a timeline and a comprehensive catalogue of Nancarrow's works.
