According to the band’s history, Portland’s Pure Country Gold was conceived as a much bigger band. When Jake Welliver and Patrick Foss — the band’s only members — first starting writing their super-fast, blues-influenced punk songs, they envisioned a multi-member revue performing the music. Foss was even attempting to write for a horn section. But that larger backing band never really materialized, and the duo developed the sound Pure Country Gold is now known for: Scratchy guitars high on reverb, dangerously loud drums and throaty vocals. (The closest thing to a horn is the occasional harmonica.) The result is a sound so intense, so without constraint, that it’s hard to believe only two men are responsible for it. Songs like “Setting Sun” off the band’s self-titled EP is deafeningly energetic. You can imagine two friends on stage, one beating the shit out a drum kit, and the other attempting a frantic pogo while playing the guitar — and all the while, the audience is dancing and shaking to Pure Country Gold’s songs.
