Hip Hop came of age inside the cinderblock walls of the Ecstasy Garage Disco in the Boogie Down Bronx. By 1980, it was the place to be as the flyest DJs and MCs honed their skills among their peers. In tribute, filmmaker Charlie Ahearn has teamed up with Grand Wizzard Theodore, inventor of the scratch, to recreate their weekly slide show as the centerpiece of Ahearn’s exhibition Scratch Ecstasy, currently on view at P.P.O.W. Gallery. Miss Rosen, who worked with Ahearn on his 2007 book, Wild Style: The Sampler, speaks with Ahearn and Theodore about the interplay between sight and sound in the development of Hip-Hop culture during its formative years.
