The Volcano Brothers are a Nashville-based band devoted to the sizzling, jazz-fueled sounds of Hawaiian music from the 1920s and ’30s — the era when steel guitars ruled the airwaves and island musicians became international stars. Led by Steve Dawson on National tricone and Weissenborn, the group brings together a cast of Nashville legends on ukuleles, upright bass, and archtop guitar to revive this vibrant, long-overlooked sound.
