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.
The 11th performance by the group will be Wednesday February 29th, 2012 from Sundown to Midnight @
150 Folsom St., San Francisco

BYO! DIY! If you're planning on setting up a performance installation- whether it's a single instrument or a complex haze of deconstructed electronics- there are some things to consider. There is no centralized PA to plug into, participants bring their own amplification. The chosen venue will have some electrical outlets and tables to set up on, but it's good to bring as much of your own gear as possible, including stands, extension cords, power strips and cables as necessary. Delicate or quiet acoustic instruments will not be heard over the cascading din during a show's zenith unless amplified.
Earplugs, drumsticks and a flashlight are good things to have at a Liquid Concrete Air Band show. Documentation of all kinds is encouraged. There is no centralized soundsystem, stage, schedule or song structure at the events. The performance slowly builds in waves over hours in a dense harmonic wall of sound that gradually dissapates as the performers eventually leave the venue. A good way to describe the less intense moments of audio would be the sound of a drum circle over feedback in a video game arcade. Recordings of peak moments tend to sound like white noise or hiss with no articulation.
