"The original source recording is from an old sound editing machine that sometimes freezes up on the operator and starts looping at that spot. 

"I had plenty of ideas, but after a lot of tinkering I found myself paring it all back until finally I was left with two copies of the exact same snippet endlessly looping, snaking in and out of sync. I was mesmerized by this simple variation of the original spontaneous glitch. 

"I tried various effects on either track like panning, filters and EQ, reverb etc. to distinguish them. But ultimately I decided I liked it best unmodified and unadorned, and that it’s not obvious which is doing what. The only editing I did was to decide how long it should be. Two cycles seemed plenty."
