The Wronglers and Jimmie Dale Gilmore

The eight members of San Francisco's Wronglers play gorgeously sweet old-time music on banjo, fiddle, mandolin and so on, and their new album, Heirloom Music, has the collective teaming up with Jimmie Dale Gilmore—the veteran Texan songman who cofounded the mighty Flatlanders. His is a voice that could melt butter in an icebox—it's that warm and soulful. String-band fans, you're in for a rare treat tonight.
