The Liquid Concrete Air Band is an interactive audio visual noise orchestra. Anyone in attendance at one of its rare and improvisational performances is a member of the group. Participants are encouraged to set up interactive installations for group experimentation. The first LCAB gig was December 10, 1993, and there have been 10 shows performed, including every Leap Year since 1996. The 10th show was held on 10/10/10 starting at 10:10 am.
