Music for Two Tape Recorders is a double cassette spontaneous composition ultimately performed by the listener using two tape players. The source tapes consist of simultaneous recordings of improvisations made by Arrington on two different tape recorders, each with their own timing, sound, and mechanical idiosyncrasies.
The original double cassette was released by sPLeeNCoFFiN in 2009 and came packaged in recycled bookcases from abundant copies of discarded romance and fiction novels, hand screenprinted here at sPLeeNCoFFiN HQ with drawings made by Arrington on a bench at the American Visionary Art Museum. Included inside the case was this explanatory note: "simultaneous recordings made on two tape recorders, 10-8-08. for best results, play both cassettes at the same time, starting at any section on either cassette."
This digital version of the release includes each side of both source tapes (A1, A2, B1, and B2), as well as four different variations of the "completed" piece (A1+A2, B1+B2, A1+B2, and A2+B1), starting at the beginning of each side.
To simulate the ideal double tape recorder environment, the two cassette sources are panned left (tape A) and right (tape B) on the combined selections.
A nice review of the release by P. Somniferum in Foxy Digitalis is available here.
