Less Than Jake have been playing music for over 15 years. Their blend of the punk and ska genres carved them out a unique niche in underground music. So unique that they didn't stay underground. With a couple major label releases under their belts, Less Than Jake have "escaped" their contract and started their own label. They are re-releasing their first record and embarking on a tour to celebrate this achievement and the fifteenth anniversary of the Warped Tour.

Warped Tour has been branching out from its image as "Punk Rock's Summer Camp" by including hip hop and rap groups. In the early years, I saw Jurassic 5 on Pier 30/32 because of Warped tour, for example. More recently, bands like Gym Class Heroes have participated. As a preview of possible upcoming rap acts, Monday's show includes a set from Chris Palko (aka Cage). Fans of intense, nontraditional rap with a rock feel like Eminem will enjoy Cage. Shia LeBeouf directed his latest video.

• Less Than Jake, Cage, and The Swellers visit the Showbox Market, November 30th. Doors at 6:30 PM, tickets are $20 advance, $23 at the door.
