Jay Z does it again! Jay Electronica performed at an exclusive music industry event in New York City a couple of days ago. At the end of his performance Jay Z announced his newest signee to Roc Nation. "We're trying to reintroduce magic to Hip-Hop," Jay-Z said. "We watched this wizard do his thing. Y'all supported him. And he's an official Roc Nation signee." The announcement comes after Jay Elect spent years building buzz on the underground circuit and snagging the attention of hip-hop luminaries such as Nas and Diddy.
