Jay Electronica is the newest member of Jay-Z’s Roc Nation team.

The mysterious New Orleans rapper joined the Brooklyn bred rapper/entrepreneur last night (November 12) as he made the public announcement at New York City night club The Box. Yet according to hip-hop personality Miss Info, the official paperwork was signed last Saturday.

“Jay-Z made me an offer I couldn’t refuse,” Elec said. “And I have the freedom I need too.”

During the celebration the two also previewed their collaborative song, “Shiny Suit Theory” which features The-Dream and Charlotte Gainsbourg.

Electronica joins Fayetteville, N.C. rep and 2010 XXL Freshman J. Cole on the Roc Nation roster.
