The distinct and fabulous halves of BeatrixJAR:http://www.beatrixjar.com were my guests this morning to talk about the Spark Festival:http://www.spark.cla.umn.edu, a 6-day multi-venue display of local, national, and even international (Amsterdam!) talents in electronic music and art. How do you define electronic music and art? We got a little talky in the first half of the 8:00 hour as we went through some of its incarnations: sound appropriation, audio collage, sound art, circuit-bending, looping…it goes on, but we wrapped it up and got back to the music. Eventually.
