#378 Run-DMC, 'Run-D.M.C.' (1984)

Arguably the first great Hip Hop album and indisputably a groundbreaking record. It was tougher, grittier and more hardcore than Hip Hop records that has come before it and was the first Rap record to be certified gold (just 9 months after it was released). The video for ‘Rock Box’ was the first rap video to be played on MTV. Imagine that – there was a time that MTV didn’t play rap music. These three broke down barriers that would ultimately change the course of music.
