Allen Iverson may have retired from basketball, but hes remaining active on the rap scene. Iverson is backing a rapper from his hometown of Newport News, Virginia named Ty Gracie. Ty Gracie has been rapping for over 10 years and has collaborated in the past with Iverson, Cru Thik and Ellis Park, LLC. The mixtape was dropped to coincide with the release of the documentary No Cross Over: The Trial of Allen Iverson. Gracie, who grew up in Bad Newz, said the documentary was an accurate reflection of the area. People from Bad Newz have a different story to tell, Gracie said. Gracie has worked a number of artists over the years, including Fat Joe, Snoop, Young Jeezy, Jadakiss, Jazze Pha, Nicole Ray and others. Atlanta rapper Yung Joc has inked a deal with Polo Grounds Music/RCA Music Group as a solo artist and will bring his Swagg Team Ent to Battery/Jive Records, also subsidiary of RCA. The deal will allow Joc to release his own material in addition to signing and developing new talent for Swagg Team. Joc is a triple threat. As an artist, executive and personality, he is now entering a higher phase of his career and I'm happy to play a part in it, affirms Bryan Leach, President, Polo Grounds Music. I feel with Pitbull, Yo Gotti and now Yung Joc, Polo Grounds has an amazing front line of smart, talented, hungry artists that will continue to show why it's still all about making hit records and outworking everyone else. Jocs new album Mr. Robinson's Neighborhood is slated for a late 2010 release.
