In the years before electronic musicians have access to computers, they are exploring the new technology of tape-recording. Using tape for composition or accompaniment can be very tedious. For example, at the time of the MOMA concert, John Cage is at work on his (somewhat more famous) Williams Mix. It involves recording 600 sounds, chopping up the tapes into pieces and splicing them into one of 8 tapes. With help, it takes him a year to complete the 4 minutes and 15 seconds piece. (It’s first heard March 21, 1953.)
Ussachevsky and Luening soon join forces to co-found the Columbia-Princeton Electronic Music Center with Milton Babbitt and Roger Sessions. Making music on really, really slow computers, they will learn, is even harder.
It’s pure Canadian, so it’s a Beauty, ey. It’s later covered by Neil Young (on 1978 album Comes a Time), and by dozens of others. Their second album, Four Strong Winds was released in April, 1964; the two were married that June.
