The POST INC. (INTERNATIONAL NOISE CONFERENCE) descends upon Eyedrum like a strange, chaotic tournament that would have a free-form feel if it weren't for all the rules. Such noisemakers as Dark Inside the Sun will be set up around the building to facilitate nonstop racket. The rules: no droning, no laptops, no mixers, and each artist gets 15 minutes to perform. Be prepared for an evening of noise from the harsh to the sublime crafted by noiseniks from around the globe. $7. 8 p.m. 290 Martin Luther King Jr. Drive, Suite 8. 404-522-0655. www.eyedrum.org.
