Woodstock singer-songwriter Simi Stone plays violin, guitar and percussion, boasts a huge, versatile voice, and commands the stage like a latter-day Tina Turner. She writes catchy pop tunes, dance numbers, and compelling, introspective folk songs, all in her signature, upbeat "Mountain Motown" style. And her band is a veritable funk-rock supergroup, including bandmates of David Bowie, Bruce Springsteen, the B-52s, and Gang of Four.
