After being lured in by a handful of dope live hip-hop jam sessions, ArtOfficial finally drops The Payback. How many hip-hop acts even know what a jam session is? Check out “Oceanography” below to get a taste, and hit the jump for the full mixtape download link.

The 12-track street album finds emcees Newsense and Logics performing over the live backing of bandmates Danny Perez, Manny Patino, Ralf Valencia and Keith Cooper, who recreate classic instrumentals by everyone from rock legend Jimi Hendrix (“Voodoo”) to jazz trio Medeski, Martin & Wood (title track “The Payback”).

The Payback isn’t just a cover album though. ArtOfficial also includes several all-new songs to help tide fans over until early 2011, when they release their next full length album, Misfits, Scholars & Mystics.
