Knut (Russian word for whip, pronounced cnoot) are a mathcore/sludge metal band from Geneva, Switzerland that formed in 1994. They started by playing in the local underground squat scene, publishing a couple of seven-inch releases as well as their first CD in 1997, titled Leftovers. This early material was put out on Snuff Records, which was run by Roderic and Didier. In 1998, Knut released their first full-length, Bastardiser, which showcased a sharper and more focused aggression, combining heavily distorted guitars, odd-time signatures, use of discordance and repetition, and harsh vocals. The band started touring Europe and shared the stage with bands like Zeni Geva, The Young Gods, Blockheads, Voivod and Neurosis. The year 1999 would prove crucial for Knut, with tours alongside Converge and Botch, both of whom had released records on the Hydra Head imprint. They brought Knut to the attention of label owners Aaron Turner and Mark Thompson, who quickly decided to reissue Bastardiser in the United States and invited them to tour. In August 2001, Knut completed an extensive trek on US soil opening for Isis, playing alongside Thrones, Converge, Keelhaul, Pelican, Premonitions of War, Anodyne, The Cancer Conspiracy, ending at New York's infamous CBGB club. In 2002, Challenger was released. Recorded at Serge Morattel's Rec Studio in Geneva, the album exceeded all expectations by pushing the envelope of heaviness, dynamics, atmosphere and chaos simultaneously (it ended in Terrorizer Magazine's end of year list next to Isis, Mastodon, The Dillinger Escape Plan, Queens of the Stone Age and Meshuggah). Knut kept touring as much as they could, but never as a full-time activity. In 2004, the band took a break while planning their next moves, writing the follow-up to Challenger and working on an experimental remix album (Alter, with contributions from Justin Broadrick, Mick Harris, Dalek, Francisco López, Asmus Tietchens). Terraformer was recorded in late 2004 in Geneva, engineered by their friend Jerome Pellegrini (former Nostromo guitarist, now in Mumakil). Originally meant to be a demo of the album, the session proved satisfactory enough for a proper release. In May 2005, Roderic joined Jesu for a European tour, filling in on drums for Ted Parsons. Before the release of Terraformer, Phil Hess quit the band. Jeremy Tavernier took over guitar duties (as, in fact, he had done on most of Terraformer) while Jerome Doudet joined on bass, quickly followed by Tim Robert-Charrue on second guitar. After several European tours in 2006, including the UK with Taint and an appearance at Hellfest alongside Opeth, Nile, Ringworm, Capricorns and Celtic Frost, Jeremy decided to leave and concentrate on his grindcore band Mumakil. Christian Valleise took his spot and Knut quickly hit the road, including Eastern Europe with fellow Swiss noiseniks Monno. In 2008-2009 the band played a number of shows, refining their new formula and taking time to write what would become their fifth studio album. In 2010, they released their first new studio album in more than five years. Not content to simply recreate the sound of their past albums, Knut strove to reinvent themselves in Wonder by incorporating new melodic elements and psychedelic ambience into their songs. Festivals and tours followed, including Europe with Keelhaul, and Russia for the first time. But in January 2012, Knut announced that they were on "indefinite hiatus".
