In July 2003 a sound no one had heard before turned up on the U.K. chart: 140 BPM, the kick drum landing on the first beat but everything else knocked off the grid, square-wave synth leads so hard-edged they sounded like they were built on PlayStation music software, and over the top of it a voice so cracked and adolescent it borders on a yelp. The man making it was a nineteen-year-old from Bow named Dylan Mills, recording as Dizzee Rascal. The album was Boy in da Corner, released on XL; that September it won the Mercury Prize. Heard in 2026, the record still sounds like nothing else on the U.K. chart of the era.

Grime had been forming for two or three years before that — out of the wreckage of U.K. garage, on pirate radio stations like Rinse FM and Deja Vu, in the bedrooms of producers like Wiley, who is the only honest answer to who invented the genre. Boy in da Corner was the moment the rest of the world noticed. For about three years afterward grime looked like it might become the United Kingdom's national popular music. Then it didn't.

What killed that first surge — the three good years just described — was a mix of factors English music journalism is still arguing about. Form 696, the Metropolitan Police's risk-assessment requirement on certain music events, made grime nights difficult to book. Major labels signed Dizzee, Kano, Lethal Bizzle, and pushed them toward more obviously chart-friendly material. The BBC playlist was friendlier to Calvin Harris, who made mainstream dance-pop, than to the underground grime MC JME.

For most of the late 2000s and early 2010s grime survived. Shut out of television and radio, it lived on the YouTube freestyle series young people watched on their phones — Logan Sama, Charlie Sloth's Fire in the Booth, and SBTV, the channel that turned unknown MCs into overnight stars — and on a handful of independent labels (Boy Better Know above all). The audience was loyal and small. By the time Skepta won the Mercury Prize with Konnichiwa in 2016 — for a record that consciously returned the genre to its 2003 sonic palette — grime's comeback was a story people had been telling for more than a decade. But around the same time, something else was quietly working its way onto London's streets.

The sound came from Chicago. Chicago drill — Chief Keef's "I Don't Like" in 2012, the entire Glory Boyz Entertainment catalog — had a slower tempo, a darker palette, and far more explicitly violent lyrics than grime. Around 2012 to 2014 a circle of young South London crews began to translate it: 67, the Brixton Hill crew whose early beats came largely from producer Carns Hill, with Section Boyz over in Croydon and the very young crew 150 also in Brixton.

The translation was not a copy. U.K. drill kept the Chicago tempo range — roughly 140 BPM, with the kick drum often hitting at half-time (felt at half the speed of the beat) — but rebuilt the drums around a much sparer, deeper 808 sub-bass (the booming low end of a TR-808 drum machine), added sliding bass figures borrowed almost directly from grime, and rapped over it in dense London road slang, packing in roughly twice the words of the Chicago originals. The result had more space than the Chicago version, low end you felt in your chest, and words that poured in without a break. By 2017, when Headie One and RV's Drillers x Trappers tapes were circulating, U.K. drill was its own thing. And by 2019 the sound that had once been refused bookings was on the chart: Headie One's "Both" reached the U.K. top 20, and in May 2021 Russ Millions and Tion Wayne's "Body" became the first U.K. drill track ever to hit number one.

The closing chapter, in a sense, was Brooklyn. In 2019 a Brooklyn rapper raised in Canarsie, Bashar Barakah Jackson — Pop Smoke — began working with a London producer named 808Melo, who had cut his teeth making U.K. drill beats. The result — "Welcome to the Party" and the Meet the Woo tapes — paired 808Melo's sliding U.K.-drill bass with Pop Smoke's deep, gravelly New York delivery, pitched almost down in the bass register. The combination sounded unmistakably like both cities at once.

Pop Smoke was murdered in February 2020. The Brooklyn drill scene he had pushed into the mainstream continued — Fivio Foreign, Sheff G, Sleepy Hallow — and within two years drill in the U.K. style was the default mode of New York street rap. The line from Bow in 2003 to Canarsie in 2019 is not a straight one, but it is real: East London exported a sound, watched it stall, exported a different one, and watched that one come back rewritten as American hip-hop. Few regional scenes have done it once. East London has done it twice.
