Americana Rock duo Dauzat St. Marie, formed in 2015 by guitarist Mat Dauzat (Seal, Kelly Osbourne, The Buggles) 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 successful U.S. arena tour supporting REO Speedwagon and an extensive amphitheater run alongside legendary duo Pat Benatar and Neil Giraldo, Dauzat St. Marie has steadily built a reputation as one of rock’s most compelling live acts. Their dynamic performances, fueled by infectious chemistry, powerful songwriting, and unmistakable vocal harmonies, have earned them devoted fans nationwide.
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 emotional 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, a major national tour, and momentum continuing to build, 2026 is shaping up to be a landmark year for Dauzat St. Marie.
“Worlds Collide” will be available on all streaming platforms beginning June 10th. Pre-Save it here: https://ffm.to/dsmwc

Dauzat St. Marie (pronounced “dough-zaht saynt mah-ree”) is the creative partnership of Heather St. Marie and Mat Dauzat, two musicians whose lives and voices have been intertwined for years. Their sound is rooted in the tradition of soulful Americana peppered with Southern Rock, Folk, and Bluegrass influences built around “lockstep” vocal harmonies that only come from a deep, intuitive connection.
On stage, the dynamic is simple but mighty: Heather’s soaring, high-velocity vocals find a perfect counterpoint in Mat’s intricate guitar work, driving rhythmic percussion, and signature vocal harmonies. The songs are honest, relatable, and explore all corners of the human experience – love, loss, and the quiet resilience required to persevere. This sincerity and authenticity has resonated on a grand scale, leading their song “Where Were You?” to the 2021 Grammy® Awards ballot in three categories, including Song of the Year, and having their song “In It Together” and its music video adopted by the American Cancer Society for a national Breast Cancer Awareness campaign by that same name.
Having toured with legendary acts like REO Speedwagon, Pat Benatar, and Rick Springfield, and having sharing stages with many more including Jefferson Starship, The Marshall Tucker Band, Rick Derringer, Sheila E., Dauzat St. Marie is very much at home on the big stage. In fact, beyond their own live show, Mat and Heather were enlisted to be Guitarist/Backing Vocalist, and Backing Vocalist for Grammy Award-winning music icon Seal on his Seal 30th. Anniversary World Tour – celebrating the anniversary of his pivotal first two albums.
