CENTER Stage: Ralph Stanley and the Clinch Mountain Boys, Laurie Lewis and Tom Rozum:

at UCLA’s Royce Hall, 2/17, 8. p.m. He is perhaps most well-known as the gravelly troubadour voice in the movie O Brother Where Art Thou?, but Ralph Stanley has been a staple in American bluegrass and folk for over fifty years. From the 1940s, in his band The Stanleys (with brother Carter Stanley), through the folk revival of the 1960s and then catapulting into worldwide recognition in the move O Brother in recent times, Stanley has remained true to his form and a virtuoso in pitch and falsetto meanderings. He is an American original, and a beacon in our living history. Get there early.
