Americana-Rock duo Dauzat St. Marie, formed in 2015 by guitarist Mat Dauzat (Seal, Kelly Osbourne) and vocalist Heather St. Marie, is set to reach new heights this summer as they join legendary Rock vocalist Sammy Hagar’s highly anticipated “Best Of All Worlds Tour,” bringing their signature blend of fiery rock energy and soaring vocal harmonies to amphitheater audiences. The tour coincides with the release of their new single “Worlds Collide” – available on all digital outlets June 10th.
The “Best Of All Worlds Tour” is celebrating Sammy Hagar’s legendary Van Halen years with an all-star band featuring Van Halen bassist Michael Anthony, guitar virtuoso Joe Satriani, and renowned drummer Kenny Aronoff (John Mellencamp, Smashing Pumpkins, John Fogerty), appearing on a stacked bill that also includes Rock Icon, and longtime Sammy Hagar friend, collaborator, and business partner, Rick Springfield.

Although the “Best of All Worlds Tour” represents some of the largest audiences of DSM’s career, with some dates expected to draw more than 25,000 fans per night, the Los Angeles-based duo is no stranger to performing on some of the world’s biggest stages.
Fresh off a massive 2024 U.S. arena tour supporOng REO Speedwagon, and an extensive amphitheater run alongside the equally legendary Pat Benatar and Neil Giraldo, Dauzat St. Marie has steadily built a reputation as one of rock’s most compelling up-and-coming live acts. Dynamic performances, fueled by infectious chemistry, masterful songwriOng, and unmistakable vocal harmonies, have earned them a legion of devoted fans worldwide.
In between Dauzat St.Marie’s tours with Pat Benatar and REO Speedwagon, the pair spent 2023 touring worldwide with music icon Seal as part of his 30th Anniversary World Tour. Dauzat was tapped to be guitarist and backing vocalist, including national television appearances on Good Morning America and the Jennifer Hudson show, and St. Marie would later be invited to join the tour as a backing vocalist as well.
“Worlds Collide” arrives at a pivotal moment for DSM. The new single captures the emoOonal intensity and anthemic spirit that has become the hallmark of Dauzat St. Marie’s sound, blending heartland rock influences with modern energy, cinematic storytelling, and Laurel Canyon charm.
With a new single, major national tours, and momentum continuing to build, 2026 is shaping up to be a landmark year for Dauzat St. Marie.
