The Fine Line Music Café is a club dedicated to live music (as opposed to a club with music). Indie rock, prog-rock, jazz, blues, funk, R & B, and world music are the mainstays, but just about every type of music has been featured here at one time or another. A different live act is featured every night, from up-and-coming local bands to national headliners, and the crowd changes with the music. No two nights are the same, and the cover charge fluctuates according to the drawing power of the band. Tickets to see national headliners are around $30 for the main floor and $60 for mezzanine.Seating is first come, first serve, unless you buy an X-Gold ticket for an extra $50, which guarantees a primo seat on the upstairs rail. The club has two levels and a dance floor, and all shows are either 18 or 21+. It’s all about the music here, so there aren’t many frills—just top-notch sound in a great setting for listening, and moving, to some great grooves.
