Della Mae

Courtney Hartman’s finely-honed musicality has firm roots in her upbringing, which included taking up violin at three, learning to play guitar at 11, and writing her first song at 12. She spent much of her childhood immersed in the bluegrass world, a factor that eventually led to her seven-year stint in Grammy-nominated band Della Mae. During her time with the band, Hartman also released a collaboration album with Robert Ellis (2017’s Dear John) and another with Taylor Ashton (2018’s Been on Your Side). Her most recent release, Ready Reckoner, features crtically acclaimed tracks inspired by her 40 days walking the Camino de Santiago, a 500-mile pilgrimage route across Spain.

Bonnie & the Clydes, Bonnie & Taylor Sims

Bonnie Sims began singing as soon as she could walk, and has been at home onstage nearly as long. Her father, Mike Cruciger, is a banjo player, songwriter and career musician, and gave Bonnie her first Martin guitar at age twelve. She picked up the mandolin at fourteen and toured for the next five years with her father, playing in and around Texas.


She then attended South Plains College where she earned a double major in Mandolin and Vocals as well as Best Female Vocalist in 2006 and 2007 and Best Female Instrumentalist in 2007.
