An extraordinary document, and one of the most important LP compilations of 1960s American experimental music. Extended Voices - "new pieces for chorus and for voices altered electronically by sound synthesizers and vocoder" - was assembled by Alvin Lucier and performed by the Brandeis University Chamber Chorus, produced by David Behrman. The six composers represented - Lucier (North American Time Capsule 1967), Pauline Oliveros (Sound Patterns), John Cage (Solos For Voice 2, realised by Gordon Mumma and David Tudor), Robert Ashley (She Was A Visitor), Morton Feldman (Christian Wolff In Cambridge), and Toshi Ichiyanagi (Extended Voices) - form as concentrated a cross-section of the American avant-garde at mid-decade as any single record managed. That it appeared on Odyssey, the budget subsidiary of mainstream Columbia, remains a fact that still requires a moment to absorb.
