He is a virtuoso of the autoharp; here's a part of MAMA's notes:
Credited with resurrecting and redefining the autoharp and widely regarded as its leading virtuoso, Bryan Bowers has enchanted audiences for over thirty years. He grew up hearing and singing the songs of the field hands and railroad workers in rural Virginia, and those songs took deep root. They found an outlet when he picked up first the guitar and then the autoharp while in college. The Dillards introduced him to the bluegrass community, and the rest is history.
