During the mid-1980s Simmons had fully developed his internal device the next big thing in music. He helped bring the Beastie Boys to a wider audience, and even revived the careers of the fading rock act Aerosmith, when Run-D.M.C. covered their 1975 hit “Walk This Way.” The two groups even made a video together, which became a classic of MTV’s first decade on the air.

But in the mid-1980s, the idea that black street kids and white suburbanites could like the same music was shocking.”
