Bitterroot began as a Boulder-based trio comprised of songwriter/vocalist/guitarist Caroline Quine, bassist/vocalist Matt Cantor, and guitarist/vocalist Kevin Johnson. The project has welcomed additional local and national artists as they add studio recordings to their songcraft, including producer/guitarist Julian Peterson. Bitterroot's Americana/folk sound features original compositions, engaging vocals, and soulful instrumentation.

Julian Peterson is a longtime Boulder/Denver-area favorite, and has contributed his considerable musical talent to numerous local artists including Erica Brown, Rebecca Folsom, and Megan Burtt. He is the founder of Wolf Den Records, a Longmont-based artist development and production label. The Julian Peterson Trio includes Leor Manelis on drums and Casey Sidwell on bass, and showcases Julian’s soulful vocals, heart-centered songwriting, and  tasty-hot guitar.
