Dar Williams has been singing, playing, and writing great music for a while, but Columbus has a special place in her heart since it’s where, in 1994, she opened for another well-known singer at Six String Concerts and gained a duet partner for her cover of a great Pink Floyd song. First person to ID the song or the partner gets a free book (pick up at WCBE 90.5FM in Columbus, Ohio). Catch her in Columbus with Six String Concerts on November 9th.
