Dave Wright of Not Breathing and his circuit bent instruments of doom (you tube)

Cool clip with Dave Wright of not breathing and carrion sound demonstrating the use of various circuit bent instruments. If you're not familiar, Circuit Bending is a technique developed by Reed Ghazala in the 70s in which one takes an existing electronic sound generator, the classic example being a speak n spell, open it up, and resolder the parts, add various switches, and uncover the atonal monsters in the circuitry. Dave makes & sells some beautiful circuit bent instruments, which he gives cool names and nice finishes to.

There are two new DIY book out about circuit bending: this one and this one
and a documentary
