What Is Grime? The UK’s 140 BPM Rap Sound

Grime is a 140 BPM East London rap genre built on square-wave bass, pirate radio and MC crews. From Wiley's Eskimo to Skepta's Mercury win, the sound explained.

Grime is a rap-and-electronic genre from East London, born around 2002 and built on sparse beats at roughly 140 BPM, with MCs trading bars in London accents over the top. It grew out of UK garage, not out of American hip-hop, and the difference shows in everything from the tempo to the way a verse is built. Among the rap subgenres it is the one with the most distinct rulebook.

The sonic recipe

Orphiq puts grime at about 138 to 142 BPM, and the tempo feels faster than it reads because the snare lands on beats two and four with little else crowding it. Drums are sparse and syncopated, with few hi-hats. The bass is often a raw square wave playing short stabs or held notes, sometimes with a clean sub underneath, and a track usually carries one melodic idea, such as a synth stab, that repeats.

The signature small sound is the “eski click,” a dry, short, ping-ponging effect that Complex’s history of eskibeat compares to 8-bit game audio. The same piece describes gliding, hollow square-wave basslines that become mournful melodies when played higher, plus plinky pentatonic lines and clipped flutes.

Then there is the structure. Beats change every eight bars, and the beat often drops out so a line can land. That eight-bar format came from pirate radio, where several MCs took turns on one instrumental. Verses stretched to 16 bars later on.

Grime pairs a snare on beats two and four with a square-wave bass stab and beats that change every eight bars.

The eight-bar block is the whole genre in miniature. It forces a punchline or a switch of flow every few seconds, which is why grime sounds urgent even when the beat is bare.

Where grime came from: East London, 1999 to 2005

The lineage runs UK garage, then 2-step, then a darker, colder offshoot. The key early document is Wiley’s “Eskimo,” an instrumental that, per Wikipedia, was made around Christmas 1999 or 2000 and first pressed on 12″ vinyl in July 2002. Wiley called the sound eskibeat, and “Eskimo” reportedly sold around 10,000 white-label copies, according to Complex.

Whether it is the first grime record is argued. Pay As U Go’s “Know We” and So Solid Crew’s “Dilemma,” both from 2000, are the other usual candidates. I lean toward “Eskimo” because it supplies the sound rather than just the attitude, but the argument is real.

The first mainstream flagship came next. Dizzee Rascal, then 18, released “I Luv U” on May 26, 2003, and Boy in da Corner followed on XL Recordings on July 21, 2003. It won that year’s Mercury Prize. Roll Deep, Ruff Sqwad and Boy Better Know all formed the crew layer around that moment.

East London itself matters here. The London Museum places grime’s birthplace in Newham and Tower Hamlets and traces its roots to Jamaican sound system culture, with council estates, youth clubs, schools and a record shop called Rhythm Division as its venues.

Pirate radio, clashes and crews

Grime was built on air time nobody licensed. Rinse FM began broadcasting in September 1994 and ran as a pirate station for about 16 years before Ofcom gave it a community licence in 2010; the legal broadcasts started February 7, 2011. Pay As U Go were among the voices on it, and Deja Vu FM was another station of the scene, per Wikipedia.

The format borrowed from sound systems: one riddim, many MCs, each taking a turn. Crews gave that structure a social shape, so names like Roll Deep and Boy Better Know worked as both labels and teams.

Clashes were the competitive layer. Jammer started the Lord of the Mics DVD series in 2004, documenting underground MC battles, and a second volume in 2006 featured Devilman against Skepta. Wiley’s Eskimo Dance raves ran in the early 2000s and returned in 2012.

Grime vs. UK drill vs. US rap

The most common outsider mistake is treating grime and UK drill as one thing. They are not.

UK drill began in Brixton, South London, around 2012 and took its cues from Chicago drill and trap, per Wikipedia’s account. Sliding 808 basslines and rapid hi-hat rolls define it; Orphiq notes the rolls are more typical of drill than of grime. Grime’s influence on drill is real but narrower: it shows up in flow and bar structure.

So grime is not drill’s ancestor in a straight line. It is a cousin that handed down some habits. The two even share a vocabulary of London accents, which is part of why they get blurred.

Against American rap, the split is cultural more than numerical. Grime inherits garage’s rhythm, the sound system’s one-riddim-many-MCs model, and pirate radio’s eight-bar turns. American trap and drill grew from a different root, and the scenes section of the site maps how each region built its own version of hip-hop. How UK rap compares with US hip-hop at large is a separate debate, and a live one.

The 2015 to 2017 resurgence

By 2014 the scene was quiet. Skepta and JME’s “That’s Not Me,” released that year, was in The Line of Best Fit’s words the scene’s biggest record in about five years.

In 2015 it caught fire, largely outside major-label control. Skepta’s “Shutdown” came out in April 2015 on Boy Better Know. It opens with a sample of a Drake Vine, and Drake later brought Skepta out at OVO Fest. The Line of Best Fit argues the revival grew through direct contact with fans rather than label push.

Stormzy’s “Shut Up” followed. He filmed the freestyle on May 17, 2015, over “Functions on the Low,” a Ruff Sqwad instrumental by XTC from 2004. The official release was September 11, 2015. After a Christmas No. 1 campaign it peaked at No. 8 on the UK Singles Chart.

The institutional proof came on September 15, 2016. Skepta’s Konnichiwa, released on his own Boy Better Know label, won the Mercury Prize at the Hammersmith Apollo, beating David Bowie’s Blackstar and Kano’s Made in the Manor among others. It was the first grime win since Dizzee in 2003.

The sales proof followed. Stormzy’s Gang Signs & Prayer entered at No. 1 on the chart dated March 3, 2017, which Official Charts called arguably the first pure grime album to reach the top.

Politics arrived in between. Boy Better Know launched the Grime4Corbyn site on May 16, 2017, before the June 8 general election, and Official Charts reported that JME had met Corbyn that week. That November, per Orphiq, the Metropolitan Police scrapped Form 696, the risk-assessment form critics said restricted grime events.

Grime today

The scene has fragmented, and I think that is a sign of success rather than decline. Plenty of MCs moved toward drill or afroswing, and the artists who stayed made records for adults. Ghetts’ Conflict of Interest debuted at No. 2 in February 2021. Chip released Grime Scene Saviour in April 2025, and Skepta featured on Fred again.. and PlaqueBoyMax’s “Victory Lap,” a No. 4 single that year. The sound also leaked into dance music: Flowdan won a Grammy in 2024 for “Rumble,” according to Orphiq.

Eight records that show the range

  • Wiley, “Eskimo” (2002): the instrumental that named the style.
  • Dizzee Rascal, “I Luv U” (2003): the sound as a pop breakthrough, from Boy in da Corner.
  • Wiley, “Wot Do U Call It?”: Complex calls it the first grime tune about grime.
  • Ruff Sqwad, “Functions on the Low” (2004): the beat Stormzy later claimed.
  • Skepta and JME, “That’s Not Me” (2014): the minimal revival record.
  • Skepta, “Shutdown” (2015): the crossover moment.
  • Stormzy, “Shut Up” (2015): the car-park freestyle that went to No. 8.
  • Ghetts, “Mozambique” feat. Jaykae and Moonchild Sanelly (single July 7, 2020): veteran grime with an outward reach.

FAQ

Who invented grime? No single person. Wiley is the usual answer because “Eskimo” and the Eskimo Dance nights built the template, but Pay As U Go, So Solid Crew and Dizzee Rascal were all part of the same moment.

Is grime the same as UK rap? No. UK rap is the umbrella, and grime is one scene inside it, with drill and afroswing sitting alongside.

Who is the king of grime? Wiley is called the Godfather. Skepta has the Mercury Prize and Stormzy has the first No. 1 album. Pick by what you are measuring.

What is 140 BPM grime? Grime’s standard tempo, roughly 138 to 142 BPM, with a snare on two and four and a lot of space.

Start with “Eskimo,” then “Shutdown,” and notice how little actually changed in a decade.
