Run–D.M.C. is the debut studio album of American hip hop group Run–D.M.C.. Produced in 1984, it was considered groundbreaking for its time, presenting a harder, more aggressive form of hip hop. The album’s sparse beats and aggressive rhymes were in sharp contrast with the light, funky sound that was popular in hip hop at the time. With the album, the group has been regarded by music writers as pioneering the movement of new school hip hop of the mid-1980s.
