The Megapolis Festival, a weekend-long, multi-venue event dedicated to the craft of DIY audio creation is looking for performances, presentations, and workshops featuring audio of all kinds for this year's model in New York City, April 19-21, 2013 at the New School. They are looking for, "circuit bending / noisemaker constructions, slumber parties, free-form audio editing sessions, interactive demonstrations, experimental musical practice and theory, film with a heavy audio component, musical performances, subversive audio tours, (un-boring) lectures, and whatever else your brain births." The theme is tourism. Some details:

"Session: 90- or 45-minute-long presentations, workshops, and the like by one or more presenters. We provide the venue. Megapolis features five 90-minute blocks on Saturday and Sunday during which time multiple sessions will happen at once. Presenters may be asked to repeat their session over the course of the two days.
Tour or Soundwalk: One or more presenters leading 15 or fewer attendees outside of festival venues. You choose the length of time on Saturday or Sunday. Usually these meet in front of the festival headquarters.
Performance: Performances take place either Friday, Saturday or Sunday night OR Saturday or Sunday day. The nighttime performance are usually ~45 minutes and take place inside. The daytime performances take place inside or out and take place during a 90-minute block during other events. Daytime performances can be part performance/part presentation. NO HIPPIE MANTRAS.
Installation: Self-sustaining and sound-based (obviously) pieces that stay put. Electricity or not is fine. For presentation inside festival headquarters and associated spaces. We encourage a period of ‘activation’ or interactive audience participation with your installation during the festival.
Miscellaneous (our favorite): Booths inside and outside festival venues, temporary radio stations, 1-800 numbers, crowd experiments, overnight or lunchtime gatherings, big wheel races captured through contact microphones and broadcast through giant speakers – essentially anything else mind-blowing you can think of outside of the above categories."
