Campbell's Jazz Soup is a Marin County-based band that plays a fun blend of 1920s, 30s, 40s, and 50s jazz and swing at events, parties, festivals, and weddings throughout the San Francisco Bay Area and beyond. Leader Brian Campbell serves up a tasty stew of hot clarinet, swinging saxophone, and hearty vocals. Mixed in to provide a feast for the ears is bluesy guitar and driving string bass. They play everything from mellow background jazz to upbeat danceable swing. The band can perform with up to seven members by including trumpet, piano, drums, and/or trombone. Their most popular sizes are the trio (composed of sax/clarinet/vocals, guitar, and bass), the quintet (add trumpet and piano or drums to the trio), and the sextet (add trumpet, piano, and drums to the trio).
