Hot Rize, an American bluegrass band, has enthralled audiences with their dynamic and authentic sound since their formation in Boulder, Colorado, in 1978. Their name, a nod to the secret ingredient of Martha White's self-rising flour—a sponsor of legendary bluegrass acts—symbolizes the band's connection to the roots of the genre and its desire to rise within the music world. Consisting initially of Tim O'Brien on vocals, mandolin, and fiddle, Pete Wernick on banjo, Charles Sawtelle on guitar, and Nick Forster on bass, the band quickly gained a reputation for their crisp and clean approach to traditional bluegrass, coupled with a modern sensibility that kept their music fresh and progressive.

With decades of camaraderie and musicianship, Hot Rize has released a number of influential albums, leaving a lasting impact on the bluegrass scene. Among their most notable works are "Traditional Ties" (1986), "Untold Stories" (1987), and "Take It Home" (1990), which contributed to their acclaim. Their performances are often distinguished by their alter-ego country-western swing band, Red Knuckles and the Trailblazers, which they would transform into mid-show, adding a playful twist to their concerts. After a hiatus in the '90s following Charles Sawtelle's passing, the band regrouped with guitarist Bryan Sutton, releasing the well-received album "When I'm Free" in 2014. Celebrating over four decades in the industry, "Hot Rize's 40th Anniversary Bash" showcases the collective's endurance and evolution, cementing their status as bluegrass titans and beloved performers.
