"Rock Box" is a song by the American hip hop group Run-DMC. The song was produced by Larry Smith and Russell Simmons and released by Profile Records in March 1984. Following the popularity of their previous two singles "Hard Times" (1983) and "It's Like That" (1983), Profile Records head suggested to the producers and group that they should attempt to record an album as they already had four songs ready, and releasing a few more would not hurt them. Despite speculating low sales from the label and the group not feeling that hip hop was a genre appropriate for a full-length album, they were given an advance to start recording. This led to Run-DMC members Joseph "Run" Simmons and Darryl "DMC" McDaniels going through their rhyme book to develop new songs, one of which would become "Rock Box".
