When the Quebe Sisters from Texas take a stage, and the triple threat fiddle champions start playing and singing in multipart close harmony, audiences are usually transfixed, then blown away. It’s partly because the trio’s performances are authentic all-Americana, all the time, respectful of the artists that inspired them the most. Doors open at 7 p.m. The show starts at 8 p.m. 1111presents.com.
