The 'Gangsta for Life', aka Mavado, has broken the boundaries for dancehall music. He has been included in a mixtape for United States presidential candidate Barack Obama, which is being produced by Russell Simmons and Green Lantern, and will be used by Obama for the duration of his campaign. Guess which song has been included? None other than the MAR tune that AHPN I'm on the Rock. Other artistes on the mixtape include Kanye West, Jay-Z, Common and Mos Def. In other news, the video for the 'Gully God's single, Last Night, directed by Little X, has finally been released, and has been in rotation on Hype TV. The track can be found on the popular video-sharing site, Youtube. Mavado is expected to release his sophomore album later this year, and plans are under way to shoot the video for I'm On the Rock, which may feature an appearance from American Gangster Jay-Z, if all goes well.
