To get a sense of Grace Potter and the Nocturnals’ sound, imagine Tina Turner fronted by The Rolling Stones. There’s Grace Potter, the leggy singer, songwriter and multi-instrumentalist fronting the Vermont-based group, who works a Tina Turner-Marianne Faithfull vibe, and favors sparkly, fringed mini-dresses on stage. Her bandmates Matt Burr, Benny Yurco, Scott Tournet and Cat Popper round out the young ensemble who have smoothly transitioned from a homegrown act to a group with national name recognition. They arrive in Iowa City on April 26 for a SCOPE concert at the Iowa Memorial Union on the heels of an April 21 concert at the Coachella Music and Arts Festival in California. Grace Potter and the Nocturnals offer an electrifying rock sound that combines elements of soul and country. The group is touring with modern country stars Kenny Chesney and Tim McGraw, but their retro sound is also similar to artists like Susan Tedeschi, Norah Jones and Adele. With performances at other festivals like Bonnaroo, Kanrocksas, and Iowa’s own 80/35, the band knows how to energize a crowd with their edgy, sultry and always infectious stage presence. The group found their experimental, genre-transcending sound through their 2010 self-titled album, which yielded fiery singles like “Paris (Ooh La La)” and “Tiny Light.” The release of the highly-anticipated LP, “The Lion The Beast The Beat,” in June will feature a few tracks cowritten by Dan Auerbach of The Black Keys. In their recordings and live performances, Grace Potter and the Nocturnals transcend the art of mere storytelling and work to convey raw emotion through their tunes.
