PSR

PSR is an ambient improv group from Urbana, Illinois, active from 2003. It begins in late 2003 as a side project of At Knifepoint, later known as Pulsar47, a post-rock band from the Champaign/Urbana area.

Formation and approach

The group starts with Dave and Aaron meeting regularly for jam sessions, often after At Knifepoint shows. From these sessions, PSR develops an improvisational sound built entirely on live, unplanned performance.

Early recordings are tested in public at very low volume through Dave’s cassette player, with the music mixed into the background of bars and other surroundings. This experimental method reflects the project’s interest in subtle texture and atmosphere.

Recordings

PSR’s full-length albums are recorded in single takes as straight-through improvisations. The group works without forethought, using this method to explore a spontaneous ambient and electronic sound rooted in experimentation.
