What is chillout music?

What "chill out" means

To chill out is to calm down after excitement, and in late-1980s British club slang it described the comedown hours after a night of acid house. Chillout music took its name from the rooms set aside for exactly that purpose: quieter spaces next to the main dancefloor where dancers could sit, talk and recover while slower, atmospheric records played. The word therefore describes a function before it describes a sound, which explains why the genre has always had blurred edges.

There is no exact technical definition. Rick Snoman's Dance Music Manual suggests that anything below about 120 BPM with a laid-back groove can qualify, and the related label downtempo usually sits around 90 BPM. Typical traits include slow tempos, sampling, a trance-like quality, beats that drop in and out, and a mix of electronic and acoustic instruments. Chillout overlaps freely with ambient, downtempo, trip hop, lounge, jazz, world music and pop.

Chillout as a music genre: the main styles

Used as a genre label, chillout is an umbrella for several electronic styles: ambient house, downtempo, trip hop, Balearic, chill lounge and, more recently, lo-fi and chillhop. They differ in texture and origin, but share slow tempos, usually below 120 BPM, space in the mix and a focus on mood rather than on the drop.

Online radio has been a natural home for the genre since the early 2000s, because a chill radio stream works like the old chill-out room: always on, never demanding attention. On POP LOUNGE CAFE chillout carries Space Drops on Tuesdays and Mystic Cafe on Sunday evenings and runs through the rest of the week.

London, 1989: the chill-out rooms of acid house

The style was born in a side room. On Monday nights in 1989, Paul Oakenfold's Land of Oz filled Heaven, a club in a converted cellar beneath Charing Cross station, with around 1,300 acid house dancers while a similar number queued outside. Upstairs, in a small VIP space called the White Room, Alex Paterson and Jimmy Cauty offered an alternative for those who no longer wanted to dance, playing Pink Floyd, Brian Eno and 10cc against multi-screen video projections for roughly a hundred people.

Their setup, according to Sound on Sound, was three turntables, a cassette player, a CD player and a 12-track Akai mixer, used to layer records, sound effects and spoken-word fragments into long, beatless collages. The six-month residency is credited with giving rise to ambient house. Mixmaster Morris, who saw the room at work, began DJing in it and went on to play chill-out rooms at many of the large parties of the early 1990s. Around the same time, Jonah Sharp's spacetime parties in London's East End were designed for conversation rather than dancing.

Paterson and Cauty recorded together as The Orb from 1988 until Cauty left in April 1990. Paterson kept the name and, with Youth, made "Little Fluffy Clouds", built on a Rickie Lee Jones interview and a Steve Reich sample. The Orb's double album Adventures Beyond the Ultraworld followed in 1991, and U.F.Orb reached No. 1 in the UK in 1992, a high point for a style that had begun as background music for a recovery room.

The KLF's Chill Out and the ambient house moment

Jimmy Cauty's other group, The KLF, gave the genre its defining title. Released on 5 February 1990, Chill Out is a 44-minute continuous piece in 14 parts that depicts a mythical night-time journey along the US Gulf Coast from Texas to Louisiana. The band said it was recorded as a single live take at Trancentral, their basement studio in a Stockwell squat in south London. Paterson later said the record drew on his DJ sessions there and that he was never credited.

The album blends synthesizers and Graham Lee's pedal steel guitar with samples including Elvis Presley's "In the Ghetto", Fleetwood Mac's "Albatross", Tuvan throat singing, train sounds and American radio broadcasts. It sold modestly at first but was later ranked by Mixmag as the fifth-best dance album of all time in 1996. As the ambient house label was used ever more loosely in the mid-1990s, it gave way to more specific terms, chillout among them.

Ibiza and Café del Mar: the sunset ritual

The second root is Balearic. In the mid-1980s DJs in Ibiza, most famously the Argentinian Alfredo Fiorito at Amnesia, mixed house, pop, Latin, funk and slower R&B-influenced records into an eclectic style later called Balearic beat. Oakenfold and his friends carried that open-minded approach back to London in 1987 and 1988. When Balearic beat faded, much of its repertoire was absorbed into chillout and downtempo, and the word Balearic is still used loosely for both.

Café del Mar, which opened in Sant Antoni de Portmany on 20 June 1980, became the focal point. Its west-facing terrace looks out over the sea, and from the early 1990s resident DJ José Padilla, who had moved to Ibiza in the 1970s, built his sets around the sunset. Crowds gathered each evening to watch the sun go down to his mix of jazz, classical, new age and electronic records, a daily ritual that turned a bar into a place of pilgrimage.

Padilla compiled the first six volumes of the Café del Mar series between 1994 and 1999. Test Pressing reports that the first sold about 5,000 copies, the second about 30,000 and the third nearly 100,000. Later volumes were compiled by other residents, including Bruno Lepretre, known as Bruno from Ibiza, who had played at the bar since 1997 and compiled Volume Seven in 2001. By April 2017, 22 volumes had been published.

Downtempo, trip hop and the compilation boom

Through the 1990s, chillout drew on neighboring styles. In Bristol, Massive Attack's Blue Lines (1991) filtered hip-hop breakbeats and sampling through dub, soul and reggae, and Portishead's Dummy won the 1995 Mercury Prize; the term trip hop first appeared in Mixmag in 1994. The Austrian duo Kruder & Dorfmeister's remixes defined a smoky downtempo sound, while Thievery Corporation brought in Brazilian influences. Air's Moon Safari (1998) added vintage synthesizers and French pop melody and sold about two million copies.

Festivals and labels gave the scene a home. The Big Chill began in 1994 as ambient parties at the Union Chapel in Islington, became an outdoor festival in 1995 and ran at Eastnor Castle from 2002 to 2011. In 1997, Rob da Bank's Sunday Best session in Clapham, built around the chill-out room ethos, led to a label that released Groove Armada's "At the River". Mixmaster Morris, who won Best Chillout DJ at the Ibiza DJ Awards in 1999, 2001 and 2010, became the scene's best-known ambassador.

Around 2000 the style reached the mainstream through compilations. Ministry of Sound's The Chillout Session topped the UK compilation chart in 2001, and countless other series followed. Zero 7's Simple Things (2001), featuring the voices of Sia and Sophie Barker, spent 56 weeks on the UK chart; Rolling Stone called it chill-out music with something for the mind as well. Bonobo, who released Animal Magic in 2000 and joined Ninja Tune in 2001, carried the sound into the following decade.

Chillout today: lo-fi, streams and mood playlists

After the compilation era, live chill-out rooms became rarer. Mixmaster Morris told DJ Mag that the smoking ban in British clubs "really killed the chill-out room", and the market for themed CDs shrank as listening moved online. The audience did not disappear; it moved to new formats. Satellite radio channels, outdoor festivals and thousands of compilations kept the sound in circulation, and in 2013 DJ Mag reported a modest revival of ambient club nights in London and the United States.

Streaming changed the genre's role again. From 25 February 2017, the YouTube channel ChilledCow, renamed Lofi Girl in 2021, broadcast lo-fi hip-hop around the clock and passed ten million subscribers in 2022. On Spotify, mood playlists such as Chill Hits reached millions of listeners by 2018. Critic Liz Pelly described this lean-back listening, in which people choose a mood rather than an artist, and warned that it risks turning music into background wallpaper. Bonobo's Migration reached No. 5 in the UK in 2017 and earned Grammy nominations.

Why people use chillout for relaxation and focus

Chillout was designed for recovery, and listeners still use it that way: to unwind, to read, to work or to study, as the full title of the Lofi Girl stream, beats to relax and study to, makes explicit. Its slow tempos, steady rhythms, long transitions and absence of sudden changes in dynamics place few demands on attention, which is why the same records suit a sunset terrace, an office and a late-night drive.

The science is more modest than the marketing. In a 2013 PLOS ONE study of 60 women, listening to relaxing music before a stress test sped up recovery of the autonomic nervous system, measured by salivary alpha-amylase, but did not lower cortisol or self-reported stress. The authors concluded that their results do not fully support music listening as a stress-management tool. Chillout can help create a calmer atmosphere, but it works best as a matter of taste and habit rather than as a treatment.
