Divide by Pi
Divide by Pi is a Chicago-area duo consisting of Aaron Krister Johnson on synthesizer and Andy Hasenpflug on electronic percussion. They formed in 2003 shortly after Hasenpflug moved to Chicago, although they had known each other from 1988, since they both attended undergraduate music school together at SUNY Purchase.
Their style is a blend of many diverse influences, creating a unique instance of electronic experimental music: early electronic music pioneers like Morton Subotnick, Iannis Xenakis, ambient music, free improvisation, and noise music. In addition, part of their sound owes it's qualities to the employment of microtonal techniques and just intonation.
