The idea was to make a robot almost entirely out of tape player parts, and mounting a tape head that continually drags itself over a flat field covered in audio tape (the TapeScape). So you're not playing a tape, you're playing on a tape. The resulting audio output is a glitchy sound experience with enormous opportunity for creative expression.
Check out how it was done.
-Discarded Chalk Board
-Audio Cassettes. Lots of em!
Find a nice big flat surface (I used a chalkboard that I rescued from the dumpster outside Laguardia High School in Manhattan) - get some 3M Super 77 and start adhering!
