His hustle and grind has officially paid off!!! JSapp MadStak now has official management representation with G.L.R. Productions. The deal comes on the heals of the two performances Sapp put on March 24th in which he amazed Yul Tunstall, C.E.O. of G.L.R. Productions. "His work ethic and passion for the music is absolutely incredible!!! Two shows, two different venues on the same day, one of which he hosted as well... I was like wow!!! Now that's an artist who's going places.", said Yul about the class act.
