In 2007 his manager and DJ Green Lantern introduced Uncle Murda's music to Jay-Z. The Brooklyn born rapper/CEO signed Uncle Murda to Roc-A-Fella Records soon after. They started to promote him immediately by placing him on a track with popular label-mates Fabolous and Jay-Z for the song "Brooklyn" (Featured on From Nothin' to Somethin' album) and everything seemed to be going well for the rapper. However in late 2008 rumors that Uncle Murda left Def Jam came about. In an interview with DJ Vlad, Uncle Murda confirmed the rumors that he has split from Def Jam and Roc-A-Fella Records claiming everything went downhill since Jay-Z's departure.
In February 2011, it was revealed that he would take part in a new Hiphop/Pro Wrestling collaboration, the Urban Wrestling Federation with taping of the first bout "First Blood" taking place in June 2011.
As of late 2012 Uncle Murda changed his name to "U.M" he was also added to the Roster on Epic Records by L.A Reid.
After releasing diss songs back and forth the two rappers with their managers decided to end the conflict. On May 9, 2008, Papoose's DJ, DJ Kay Slay, announced that the two rappers had ended the feud on his radio show. Soon after, the two rappers appeared on the same song together for the remix of "Don't Take It There" also featuring Junior Reid, Tony Yayo, Jim Jones, and Sheek Louch and have collaborated since then.
