J. Cole proves he has many tricks up his sleeve, as the latest stop on his Dollar & A Dream tour provided fans with yet another surprise guest, Kendrick Lamar.  The two electrified the crowd with a performance of  their latest track "Forbidden Fruit" in Houston. The track is a standout on Born Sinner, as Cole smoothly samples the classic record "Electric Relaxtion" by A Tribe Called Quest. Kendrick also stuck around to perform the Cole produced "HiiPoWer" and "Don't Kill my Vibe" off GKMC.
