This show, first broadcast on April 6, 2018, was the last program in my series “A 21st-Century Guide to 20th-Century Music.” It concludes my survey of the history of electro-acoustic music by focusing on music that combines synthesized sound with conventional instruments or voice. In the music of Mario Davidovsky, Milton Babbitt, and Robert Ashley, the electronic music created is heard on a tape, which is played with the live musicians; Karlheinz Stockhausen employed sine-tone generators to transform the sound of an orchestra as it performed; and Sun Ra played the Mini-Moog synthesizer along with members of the Arkestra. Included are quotations from my own interviews with Davidovsky, Babbitt, and Sun Ra. The works heard are:

MARIO DAVIDOVSKY
Synchronisms No. 1 (1963)

KARLHEINZ STOCKHAUSEN
Mixtur (1964, rev. 1967)
MILTON BABBITT
Correspondences (1967)
SUN RA
