It wouldn’t be wrong to say that Shannon and the Clams was formed by accident. Just outside the invisible borders of Oakland’s warehouse music scene, Shannon Shaw was absorbed in studying illustration at California College of the Arts, a 100-year-old institution that draws freaks into the city from across the country. For many, the school serves as a gateway into the sprawling music underground that agitates beneath the Bay Area, as a hub for fliers for illegal parties in backyards, basements, and overpasses. During a bout of depression, Shannon took up a neglected bass guitar that had been a gift from an ex-boyfriend years earlier and played it for the first time, writing in a raw and untrained way.
