Amazon.comThis is the only recording of three of the eight works heard here. Arditti uncovers a powerful early work by Alvin Lucier, who is known primarily for his electronic music. Lucier's Fragments (Rome, 1961) has each player performing at his own speed, and the quartet improvising on a single pitch! The other two premiere recordings are Jay Yim's Autumn Rhythm, named after a Jackson Pollock painting, and La Monte Young caught in his Webern stage (1956). John Cage's Four, written for the Arditti Quartet, gets a 20-minute reading. The remaining quartets by Nancarrow, Ives, Feldman, and Carter are wonderful American standards. --Robert Reigle
