The Pit Stop is going legit. Though the Oak Bluffs club has been putting on unofficial shows for several months, it just recently was granted business and entertainment licenses from the town. Now it’s ready to celebrate with a weekend full of concerts.

The kickoff to the Pit Stop’s official run begins tonight with free live music by Willy Mason, Nina Violet, Marciana Jones and Adam Lipsky. On Saturday there will be a CD release party for Master Exploder. Doors open at 7 p.m. on both nights and music starts at 8 p.m.
