The Ark's 50th reunion shows bring back to the stage some musicians who are old friends of the club—and who represent a collection of musical knowledge unlike anything you're likely to hear just about anywhere else. Come join the celebration! Tonight's show includes The Chenille Sisters, Ann Arbor's girl-group gift to the world, along with three classic folksters: Ray Bierl, Bob White, and Ed Trickett. Unannounced special guests are a strong possibility!
