Confield is the sixth studio album by British electronic music duo Autechre. It was released on 30 April 2001 through Warp Records on 2xLP, CD and digital services. The album marked a significant shift in sound for the duo, moving towards abstract and experimental tracks instead of the previous warm, ambient sounds of Amber and Tri Repetae. Confield was the first Autechre studio album to utilise generative programs such as Max. The album received general acclaim; critics enjoyed its experimental nature, though some thought it was overly robotic and unapproachable.

Autechre are a British electronic music duo composed of members Rob Brown and Sean Booth. After the release of the self-titled album Lego Feet in 1991, their first project under the Autechre name would come with the release of Cavity Job later in December. The duo's first studio album, Incunabula, was a surprise success. After signing with Warp Records, the duo would go on to release albums such as Amber and Tri Repetae, which were received mostly positively by critics.

With Confield, the duo largely abandoned the ambient and melodic styles of their earlier works such as Amber and Tri Repetae in favour of more chaotic and abstract sound palettes. As their style grew more experimental, Confield and their later albums would see the use of software like Max to form the basis of songs rather than physical synthesisers. According to Booth, most tracks from Confield originated from experiments with this software that would not fit in with a club environment.

Confield and later releases by the duo such as Exai would make use of generative sequences done through Max. Brown and Booth later noted the use of something called "the system" while making their music; a large network of synthesisers and other digital processes. The duo have also stated in interviews that the music created by this system is not entirely random, and still requires human control to guide and change tracks.

Confield has been described as IDM, experimental, electronic, electronica, and abstract. In a review for Pitchfork, Malcolm Seymour III described how abstract the album was in comparison to the duo's previous projects. Seymour III also stated how Confield was a lot less accessible to newer listeners compared to Autechre's previous projects. Mike Barnes of The Independent called the music harsh but beautiful, noting its repetitive beats and its complex rhythms throughout. In a retrospective review of Tri Repetae for The Quietus, Gary Suarez noted how the album treated melodies like "bitter foes", with sounds being timestretched and manipulated. Louise Bradbury of OffBeat noted how melodies "took secondseat" with Confield, with sweeping percussive elements being the main focus of the album.

Tony Naylor of NME called "Sim Gishel" a track with atmospheric, stifled melodies and disjointed beats. "Eidetic Casin" was also noted for its "iridescent chimes". Pascal Wyse of The Guardian commented on the "strange sampled snoring" of "Uviol" and the melodies resembling voices on "Lentic Cathachresis". In a review for AllMusic, John Bush described "Cfern" as a track that "keeps listeners guessing" with conflicting rhythms and confusing beats. Bush also said the opener "VI Scose Poise" contained "bouncing-ball-in-a-ring-modulator production" along with melodies in the minor key. Seymour III compared "Pen Expers" to drill 'n' bass with "vacuum-navigated" percussion. "Parhelic Triangle" contains a brooding baseline and a variety of chimes; Seymour III compared the track to "Acroyear2" from LP5. In Sounding Art, Katharine Norman stated "Bine" contained warped drum machines and disordered sounds. Norman compared the track to a "machine gone mad".

Confield received acclaim from critics. At Metacritic, which aggregates scores from mainstream critics and assigns a weighted average, Confield has an average score of 82 based on 10 reviews, indicating "critical acclaim".

Reviewing the album for Pitchfork, Malcolm Seymour III gave the album an 8.8 out of 10, concluding that Autechre fans would feel alienated by the release. However, Seymour III also noted the high production value of the album and that it was "thought-provoking". Tony Naylor of NME gave Confield an 8 out of 10, stating the release was not "emotionally detached" and calling it both "biologically warm" and imaginative. Spin's Eric Weisbard gave the album a 7 out of 10, concluding that the album was a variety of six minute tracks that set texture-beats against drone-shimmers. Confield was covered in a 2001 issue of Billboard, stating that the duo's music would likely be picked apart, as well as calling them influential. It was also noted that the audience should instead "sit back and let [the album] wash over [them]". In a review for Blender, Douglas Wolk described how the duo had moved away from traditional compositions to fractured beats that "detonate in flurries". Wolk also noted how Autechre "[pushed] the outer limits of their craft" with Confield. Louise Bradbury of OffBeat gave a positive review, calling the album "breathtaking".
