With two songwriters, six albums, and more than a thousand shows under their belt, The Coffis Brothers have earned their reputation as modern-day torchbearers of all-American rock & roll. It’s a sound caught halfway between amplified Americana, acoustic folk, roadhouse R&B, and electrifying roots music, crafted by a pair of California-born siblings who’ve been sharing the stage since childhood, and the five piece band filled out by Kyle Poppen (guitar), Aidan Collins (bass), and Cory Graves (drums).

That sound reaches a new peak with Kaw-fis Bruth-urs. The band’s third collaboration with Bay Area legend (and longtime Mother Hips frontman) Tim Bluhm, who serves as the album’s producer, Kaw-fis Bruth-urs finds Jamie and Kellen Coffis letting their guard down, enjoying the creative ride as much as the destination itself. For every signature-sounding song like “Cut Right Through” — a heartland rock anthem built for highway drives and long horizons, as sunny as the band’s Golden State homeland and as hook-driven as a Tom Petty classic — there’s another track that stretches the band’s sound into new territory. The result is The Coffis Brothers’ widest-ranging album yet, running the gamut from bluesy, blue-eyed soul (“Face the Music”) to jangling, harmony-heavy power pop (“Do You Want To”).
