Crumb’s affinity for what the New York Times describes as “exotically sensual sound colors” and “extravagantly mystical allusions” is on full display in the two pieces featured here: Ancient Voices for Children, a song-cycle based on texts by Garcia Lorca, and Music for a Summer Evening (Makrokosmos III), which both references Bartók’s influence on the composer and uses techniques and sonorities uniquely Crumb’s own.
