The early 1980s were an exciting time for music. Hair metal bands were selling out stadiums, while clubs and house parties in New York City had spawned a new genre of music. At the time, though, hip hop's reach was limited, an art form largely ignored by mainstream radio deejays and the rock-obsessed MTV network.

But in 1986, the music world was irrevocably changed when Run-DMC covered Aerosmith's hit "Walk This Way" in the first rock-hip hop collaboration. Others had tried melding styles. This was different, as a pair of iconic arena rockers and the young kings of hip hop shared a studio and started a revolution. The result: Something totally new and instantly popular. Most importantly, Walk This Way would be the first rap song to be played on mainstream rock radio.

In Walk This Way, Geoff Edgers sets the scene for this unlikely union of rockers and MCs, a mashup that both revived Aerosmith and catapulted hip hop into the mainstream. He tracks the paths of the main artists--Steven Tyler, Joe Perry, Joseph "Run" Simmons, and Darryl "DMC" McDaniels--along with other major players on the scene across their lives and careers, illustrating the long road to the revolutionary marriage of rock and hip hop. Deeply researched and written in cinematic style, this music history is a must-read for fans of hip hop, rock, and everything in between.
