The Bronx, 1973

Picture this: August 11, 1973. A rec room at 1520 Sedgwick Avenue in the West Bronx, New York. A teenager named Cindy Campbell is throwing a back-to-school party to raise money for new clothes. Her older brother Clive, a Jamaican-born DJ who goes by DJ Kool Herc, is on the decks.

That party is the date most people point to as hip-hop's birthday. When hip-hop turned 50 in 2023, this is the party everyone was celebrating.

The Bronx was going through it

In the early '70s the Bronx was in rough shape. A highway had been cut straight through neighborhoods, landlords were abandoning buildings, and fires were everywhere. Kids didn't have much money or much to do.

What they did have: records, block parties and each other. Hip-hop was built out of whatever was lying around. Two turntables, a mic, spray paint and a piece of cardboard to dance on.

Herc's big idea: the break

Herc noticed the dancers went hardest during the break, the short part of a funk or soul song where the vocals drop out and it's mostly drums. So he got two copies of the same record and switched between them, playing the break over and over. He called it the Merry-Go-Round.

That loop is the DNA of every hip-hop beat since. And the dancers who went off during the break became the b-boys and b-girls.

The four elements

Hip-hop was never just music. From the start it was four things happening at once:

• DJing: the turntable side, cutting and looping records.
• MCing: the person on the mic hyping up the crowd. This became rapping.
• Breaking: the dance. It even made its Olympic debut at Paris 2024.
• Graffiti: writing your name on trains and walls so the whole city saw it.

The Universal Zulu Nation, a Bronx collective, later added a fifth element: knowledge. Knowing where all this came from. Which is literally what you're doing right now.

Then came the pioneers

• Grandmaster Flash made DJing technical, with precise mixing and cutting between records on beat. His crew member Grand Wizzard Theodore is credited with inventing the scratch.
• MCs went from hyping up the crowd to telling full stories over the beat.
• In 1979, the Sugarhill Gang's "Rapper's Delight" became the first rap single to crack the Top 40. A lot of Bronx pioneers were annoyed, because the group had been put together by a label and wasn't part of the scene. But it proved rap could sell.

In 1982, Grandmaster Flash and the Furious Five dropped "The Message", a song about poverty and stress in the city. It showed rap could say something serious, not just keep the party going.
