With their 1979 hit "Rapper's Delight"—the first Top 40 rap single ever—The Sugarhill Gang introduced the world to hip-hop, sampling, and the way the East Coast got down, from New Jersey to the Boogie Down Bronx. "Hot Hot Summer Day" and "Showdown" further exploit the party-rocking formula, pairing rubbery funk and disco loops with uptempo rhythmic raps to keep the dance floor rocking. The silky slide of "Girls" makes disco's influence apparent, while "Apache" turned the Incredible Bongo Band's original into a Lone Ranger-referencing breakdance staple.
