Pinhead Gunpowder has been played on NTS shows including Yesterday's News, with Mahagony first played on 24 April 2019.

Pinhead Gunpowder are an East Bay punk rock band consisting of Aaron Cometbus (drums, lyrics), Bill Schneider (bass), Billie Joe Armstrong (guitar, vocals) and Jason White (guitar, vocals).

Sarah Kirsch (guitar, vocals) of Fuel (think Monuments to Excess) was in the band when they first formed in 1991, but eventually left, 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 discovered serendipitously by Aaron Cometbus during one of his many dumpster diving adventures. Aaron Cometbus, who releases the "Cometbus" fanzine, has played with many other bands, such as Crimpshrine and Cleveland Bound Death Sentence, and has long been a part of East Bay's punk culture.

Pinhead Gunpowder's music has been released through Lookout Records and Adeline Records (the latter co-owned by Billie Joe Armstrong and a major occupation of Jason White).
