"Walk This Way" is a song by the American rock band Aerosmith. Written by Steven Tyler and Joe Perry, the song was originally released as the second single from the album Toys in the Attic (1975). It peaked at number 10 on the Billboard Hot 100 in early 1977. This version of "Walk This Way" charted higher on the Billboard Hot 100 than the original, peaking at number 4, becoming Run-DMC's biggest hit. In addition to being one of the songs that helped break Aerosmith into the mainstream in the 1970s, it also helped revitalize their career in the 1980s when it was covered by Run-D.M.C. and it became an international hit. This cover was a touchstone for the new musical subgenre of rap rock, or the melding of rock and hip hop.
