According to the February 2006 Q magazine, Run-D.M.C. stumbled across this song during a search for breakbeats to use during DJ sets in the early ’80s. They didn’t know who Aerosmith were and thought the band was called Toys In The Attic because that was the album title. Rick Rubin, who was producing Raising Hell, was a huge fan of Aerosmith and suggested to Jam Master Jay that he call Perry to ask if he and Tyler would play on their cover version.
In the music video, the two groups are battling behind a wall to an eventual break through the wall. This is a video from the MTV Video Music awards when Aerosmith and Run DMC shared the stage for the first time.
