No, the Comet isn’t hosting an Alcoholics Anonymous
meeting during the Capitol Hill Block Party (though maybe they
should). Rather, they’re throwing their own adjoining party with
NYC noise-jammers Aa (pronounced “big a, little a”). Aa are
three guys on percussion and one on samplers and synthesizers, making a
rhythmic racket. Their aerobic live shows are part sweat-soaked
vision quest, part ritual dance. With Das Llamas and the
Pleasureboaters. (Comet, 922 E Pike St, 323-9853. 11 pm, $5,
21+.)
