SIX is a surround-sound performance series in its 10th installment, celebrating experimentalism in electronic music with an array of artists from Portland and beyond, spotlighting several multidisciplinary artists who utilize various combinations of sound, video, and performance art as a medium for presenting an audible equation. This relies on an improvisational relationship between sound and the perception of the audience to create an interactive experience. Among the eight artists performing are Justine Highsmith, who is interested in the performative possibilities of sound as sculpture, and Anita Spaeth, an experimental artist who works with vocal looping and effected objects.
