X singer-guitarist John Doe brings his folk trio to the Music Supper Club tonight at 7:30. The group, which also includes bassist Kevin Smith (Willie Nelson) and drummer Conrad Choucron (NRBQ), just released Fables in a Foreign Land, a collection of mid-tempo folk-rock tunes characterized by Doe's languid vocals and sparse arrangements. Tickets cost $22 in advance, $28 on the day of the show.
