(UPDATE: Bobo and Gamelan Cakewalk are out on Bengal Burlap, available at Bandcamp.)
I marveled at the remote on/off switch on the garden-variety mic that came with a cassette recorder. At some point I clued in on how that on/off switch could be used during playback when the mic was plugged in.
Thus the coming & going of that voice and squealing saxophone in the left channel: it's a tape recording that keeps cutting in and out as the remote switch is turned on and off.
The bargain basement tape effect in this instrumental was the cue/fast forward button on the tape deck. I liked this piece but found it a bit long. This was a cassette recording and I lacked the savvy or the nerve to splice tape.
So I just hit the cue button during playback to move things along. I thought of it like some Dada editing method. And I liked that chattering, chirping "screeeeeee!" sound.
