audio capture/ creation

well i had a very disappointing experience with this project. i had an elaborate plan to score a piece for my capture, and record it in York's recital hall along side my fourth year composition class' pieces. i wrote out a score for 2 adapted violins (smal plastic tubes covering two strings on each instrument) an upright bass, an adapted trombone, bowed cymbols and an instrument of my own creation. i cut plastic tubes and attached it t a motor, which was controlled by a foot pedal to adjust the speed. as the speed increased the spinning tubes tone would rise. with this i had 3 cell phones on stage sitting beside amps, and the phone numbers written out so the audience could read them. the concept was people in the audience call the phones, the interference comes through in the amps as beeps and static, and the answering machine of each phone had the melodies of the piece recorded as the greeting, all the music on stage was an accompaniment to these melodies.
well it was performed and went over fairly well i feel, but for some unknown reason to me this is the first performance in the recital hall this year that was not recorded. i have no capture of it, so i can't use this anymore. it is my own fault for assuming it would be recorded, i should have investigated before the concert but it is a very big disappointment.
the pieces i am submitting is my plan B, a lot of the steam i had for this project i lost after the performance, but i am relatively happy with the final outcome.
