Counter)Induction had its most recent concert at the Tenri Institute on Friday, May 20, 2011. The room is small and intimate, and it contained eight speakers and a massive amount of cabling, as well as a couple of computers, a piano, a drum set, xylophone, chimes, and wooden blocks.
The speakers (and some sophisticated software to go with them) were from Viewsonic of Arlington, Va. Douglas Boyce, composer of the first piece to be performed, told me that the software has a fantastic GUI that allows musicians to move music around in a circle from speaker to speaker and add speakers as necessary.
