From our Beat Builder program to our recent experiments with John Cage-style prepared piano, BAM has always been big fans of experimenting with sound. For our upcoming Makeshift on February 4th we've been developing several new experiments around the concept of Musique concrète, including taking it very literally and casting contact microphones inside of concrete slabs. 

From Wikipedia:

Musique concrète  is a genre of electroacoustic music that is made in part from acousmatic sound, or sound without an apparent originating cause. It can feature sounds derived from recordings of musical instruments, the human voice, and the natural environment as well as those created using synthesizers and computer-based digital signal processing. Compositions in this idiom are not restricted to the normal musical rules of melody, harmony, rhythm, metre, and so on. Originally contrasted with "pure" elektronische Musik (based solely on the production and manipulation of electronically produced sounds rather than recorded sounds), the theoretical basis of musique concrèteas a compositional practice was developed by Pierre Schaeffer, beginning in the early 1940s
