Daniel Peterson and Erik Parr formed Haarp late in 2006 when Erik was commissioned to make a soundtrack for a research DVD at the University of Washington.  The first 3 projects were soon formed which consist of processed bass and guitar; the third made it onto the DVD.  Project 4 was created in fall of 2007 in a similar fashion but also includes processed whistling.

Daniel Peterson was born and raised in Honolulu, HI.  He currently attends the University of Washington studying music composition under Juan Pampin.  His interests include spectral analysis, ambisonics and the exploration of the relationships between literature, philosophy and music.
