EPMD was the duo of rapper Erick Sermon and dj Parrish Smith. They debuted with the single It's My Thing (1987) and the album Strictly Business (1988 - Priority, 2010), containing Strictly Business and You Gots to Chill. Their aggressive stance and sample-dependent composition were more focused on the sound than on the message; and they emphasized technology rather than street culture on the carefully orchestrated Unfinished Business (1989), Business As Usual (1990), and particularly their last album, Business Never Personal (1992).
