Born in Berkeley, California, Cometbus started writing fanzines in 1981 with Jesse Michaels of Operation Ivy, and started his own after Michaels moved to Pennsylvania in October 1981. Aaron became an active participant in the Gilman Street Project and was a founding member of Crimpshrine, a highly influential East Bay punk rock band, which also featured Jeff Ott. After the demise of Crimpshrine, Aaron formed Pinhead Gunpowder with a handful of people from the East Bay punk scene, including Mike Kirsch, Jason White and Billie Joe Armstrong of Green Day.
Aaron has also played in a multitude of short-lived bands that generally release just a seven-inch or two before breaking up, some of which include Astrid Oto, Cleveland Bound Death Sentence, Scooby Don't, Shotwell Coho, The Blank Fight (which included Rymodee of This Bike Is A Pipe Bomb), EFS, Redmond Shooting Stars, Mundt and The Retard Beaters, T. Zatana, Colbom, and Harbinger (which also included Robert Eggplant, formerly of Blatz, and John Geek of Fleshies). He briefly played drums in the SF anarcho-syndicalist group Strawman. He has been known to sit behind the kit for This Bike Is A Pipe Bomb from time to time. He recently played in The Thorns of Life, a short-lived project with Blake Swarzenbach and Daniela Sea.
