Kieran Hebden (born September 1977), known as Four Tet, is an English electronic musician. He came to prominence as a member of the post-rock band Fridge before establishing himself as a solo artist with charting and critically acclaimed albums such as Rounds (2003), Everything Ecstatic (2005) and There Is Love in You (2010). In addition to his eleven studio albums as Four Tet, Hebden's work includes a number of improvisational works with jazz drummer Steve Reid and collaborations with Burial and Thom Yorke.

Alongside his own recordings, Hebden has produced albums by American improvisational group Sunburned Hand of the Man and Syrian dabke singer Omar Souleyman, and arranged the 2021 Madlib album Sound Ancestors. He has also remixed tracks by artists including Aphex Twin, Bicep, Explosions in the Sky, Bloc Party, Super Furry Animals, Radiohead, Ellie Goulding, J Dilla, Lana Del Rey, Manic Street Preachers, Sia, Black Sabbath and Madvillain; several of these were collected on the compilation Remixes (2006). He has additionally performed DJ mixes, including sets with American producer Skrillex and British producer Fred Again.

Hebden's first solo release was the 1997 single "Double Density", released on the Output label under the artist name 4T Recordings. He began releasing material as Four Tet in 1998 with the 36 minute, 25 second single "Thirtysixtwentyfive". Later that year, he released another single, the jazz-influenced "Misnomer". 1999's Dialogue, again on Output, was Four Tet's first full-length album release and fused hip hop drum lines with dissonant jazz samples. This was followed by the double A-side single "Glasshead"/"Calamine", which was to be Four Tet's last release on Output. In late 1999, Warp Records released Warp 10 + 3: Remixes, a tenth-anniversary compilation of remixes of Warp tracks. Hebden contributed a remix of the opening track of Aphex Twin's Selected Ambient Works Volume II, which was considered to be his break-out release.

In 2001, Four Tet's second album Pause was released on Domino Recording Company and found Hebden using more folk and electronic samples, which was quickly dubbed "folktronica" by the media and press in an attempt to label the style (often also applied to artists such as Isan and Gravenhurst). Rounds was released in May 2003. Three singles were released from the album: "She Moves She", "As Serious as Your Life" and "My Angel Rocks Back and Forth". This last single was released as an EP featuring remixes by electronica duo Icarus and Isambard Khroustaliov along with additional Four Tet tracks "I've Got Viking in Me" and "All the Chimers". An accompanying DVD featured all of Four Tet's videos to date. In addition, the closing track "Everything is Alright" was featured in a U.S. Nike commercial in 2001 and 2002.

At the beginning of 2003, Four Tet opened for Radiohead on their European tour. A remix of the song "Scatterbrain" from Radiohead's sixth studio album Hail to the Thief was released in November 2003 as a B-side to the single "2 + 2 = 5" and later included on their 2004 EP COM LAG (2plus2isfive). Furthermore, Hebden was among the people thanked by Radiohead in the booklet accompanying their 2007 In Rainbows "discbox" release.

A live album named Live in Copenhagen 30th March 2004 was released in April 2004 as a limited edition, available exclusively from the Domino Records website.

In March and April 2005, Four Tet performed two shows of improvisational music, in collaboration with jazz drummer Steve Reid, in Paris and London. He also appears on Steve Reid Ensemble 2005 album Spirit Walk. This collaboration was extended into a series of international tours, and the release of two albums, The Exchange Session Vol. 1 and The Exchange Session Vol. 2 over the course of 2005 and 2006.
