EPMD's way ahead of these new jacks. The legendary Long Island duo has already broken up and gotten back together — twice. In 1993, Parrish Smith and Erick Sermon parted ways amid accusations of shady business. Four years later, after a few rounds of diss tracks and interview smack-talking, they reunited with Back in Business, but then went back to their respective solo careers in 1999. In 2006, they began rocking shows together again, and then released their seventh album, We Mean Business, in 2008. They've since continued to perofrm together -- here and there.
