So, then... if Mike Battle starting making prototype 'Plexes in the late 50's, was he aware of, or involved in, the activities of Riley, Oliveros, Reich, et. al. at that time?
I asked him if he'd heard of Terry Riley, but he said not.
Was it really, as it seems, that an Echoplex made it into Riley's hands... he explained it to someone... who implemented the idea in a different way (large tape decks)... which Riley tagged the "time lag accumulator"... which Riley continued to use and others used later as live looping devices... sorta like that?
I talked to Terry on the phone at some length and he never mentioned the Echoplex. He was working with two monophonic Wollensack tape decks circa 1959-60. He made "Mescalin Mix" in 1960 by using one of the decks as a source, with a very long loop os source material (across the room, out the window into the yard, around a wine bottle and back in the window) and used the sound-on sound function of the second deck to layer sounds. He played the resulting piece for the French radio engineer, who then came up with the idea for the two-deck system that became the Time Lag Accumulator. When Terry returned from France he implemented the system on two Revox decks.
There is a little confusion about dates in all this, since Ramon and Pauline claim there were some long-delay dual-machine performances circa 1960-61. My suspicion is that this may be true, but that adding the feedback component to the circuit may have come later. Time to talk to them all again?
