Re: Time Lag Accumulator, Frippertronics, Eno

Not just that.  I recall an article in Musician (I think) with Fripp, where
he described the setup.  In particular I remember him having a
compressor-limiter in the chain on the way to the first tape deck, and
saying something about it reducing the accumulation of noise on the final
tape reel.  After a disasterous first experiment (without a
compressor-limiter box, just the guitar, fuzz, small stone into the loop)
with a pair of decks, I completely agreed.  I've got the recording of it
still, you've got an awful kind of subharmonic drone that increases over
time and eventually dominates the entire piece.  Underneath this, in time
with the length of the resulting loop, is a peaking "shiirp!" sound that
also gets louder and louder over time.  I decided it was best thought of as
a musique concrete experiment, as well as a reminder of the old days.

And secretly wished for a pair of high-end Revoxes or Sonys to make a tape
loop as long as possible.  Ah.
