The Deltaz

The Deltaz are a brother duo blending Americana, blues-rock, and raw sibling harmonies into a sound rooted in American traditions. Raised in the hills outside Los Angeles, they built their early reputation in Southern California before mentorship from bassist Rick Rosas and tours with The White Buffalo expanded their reach. After losing their home and studio in the 2018 Woolsey Fire, they rebuilt their lives in Nashville, culminating in Give It All to You—a 12-song album recorded live with Grammy-winning producer Mark Neill and released in September 2025. Featuring bassist Alison Prestwood and showcasing the brothers’ tight vocal blend and groove, the record reflects both their Southern influences and personal transformation. Now fixtures in the Tennessee scene and active in the Mississippi blues community, The Deltaz continue to craft music that’s rich in resilience, connection, and the deep-rooted spirit of American roots music.
