Big Sam's Funky Nation is a driving force of Urban Funk. Ryan White, of the Oregonian says the band is "tight enough (and hot enough) to turn coal into a diamond!" The band is led by trombone powerhouse, Big Sam Williams, formely the trombonist for the Dirty Dozen Brass Band, who the San Francisco Chronicle calls "the top man on the slide trombone in the birthplace of Jazz." Combining his distinctive trombone riffs with a call-and-response MC style Big Sam refuses to let the audience sit still. Between the band's solos and his trombone riffs, Big Sam second-lines and gets the crowd going.
