Pinhead Gunpowder is an East Bay[California] punk rock band consisting of Aaron Cometbus (drums, lyrics), Bill Schneider (bass), Billie Joe Armstrong (guitar, vocals) and Jason White (guitar, vocals). Mike Kirsch (guitar, vocals) was part of the original band formed in 1991 but left the band citing personal differences with Green Day (the band for which Billie Joe Armstrong is most famous). The band's name comes from a brand of "high octane" green tea served at the Arcata co-op and discovered serendipitously by Aaron Cometbus during one of his many dumpster diving adventures.

Aaron Cometbus, who releases the "Cometbus" fanzine, has played in many East Bay area bands such as Crimpshrine. Bill Schneider is now Green Day's guitar tech/tour crew manager. Jason White played guitar on two Green Day tours and currently plays with The Big Cats.
