While these performances occurred on opposite coasts, the source material is closely aligned in both concept and process. These works highlight Gregg's ongoing preoccupations with sound and setting, incorporating the focused blend of acoustic and electronic sources that Kowalsky is already well known for. 'Electronic Music for Square and Sine Waves' documents Gregg Kowalsky's contribution to the 2011 Activating the Medium festival in San Francisco. This commissioned piece continues Kowalsky's interest in how sound engages, manipulates and modifies one's awareness of space. 'For Baroque Lute, Tapes and Resonant Space' documents Kowalsky's on going tape chants process, a project previously realized on both his Battery Townsley (2011) and Tape Chants (2009) LPs. For this iteration, Kowalsky tuned square and sine waves to Dutch lutanist Jozef van Wissem's lute and then played these recordings through cassette players.
