Sampled: Classic Rock, Vol. 1

Rap started with disco breaks but never forgot shredding guitars. The '80s Bronx crew Boogie Down Productions took AC/DC's electrifying “Back in Black” riff for the backbone of their early gangsta rap tale “Dope Beat”. The practice continued decades later, as Kanye West redrew the slow marching chug of Black Sabbath's “Iron Man” into the lush “Hell of a Life”.
