TesseracT is a progressive metal band from Reading, UK, that uses math metal, djent, ambient and technical metal elements in their music. TesseracT started out back in 2003 as an archetypal djent band in then-teenage Acle Kahney's bedroom. What started as an outlet for creativity and experimentation grew and Kahney posted clips of his technically heavy guitar work on forums such as Sevenstring.org, taking the feedback on board and gradually improving his technique. It was in this way that a community of bedroom producer-musicians were spawned and this new wave of progressive music was created, along with names such as Misha Mansoor (Periphery), Paul Ortiz (Chimp Spanner) and John Browne (Monuments), who was a bandmate of Kahney's in Fellsilent.
The word 'djent' is an onomatopoeia for a heavily palm-muted, distorted guitar chord. It was coined by Meshuggah guitarist Fredrik Thordendal, though generally made popular by Mansoor on the band's online forum and it was there that Kahney originally learned the technique. When Thordendal heard and commented on some of Kahney's riffs, it was all the encouragement he needed to forge ahead.
Embodying the international vibe of the genre, Frenchman Juilien Perier initially supplied vocals but the logistical difficulties meant that he could not join the band permanently. The line-up was completed by Jay Postones on Drums, James Monteith on Guitar and Amos Williams on Bass. Monteith and Williams brought along with them the vocalist of their previous band 209, Abisola Obasanya. TesseracT released a three-track demo with Obasanya on vocals. In 2009, the band parted ways with Obasanya and chose Dan Tompkins (SkyHarbor, In Colour, ex-First Signs of Frost, Piano) to take over vocal duties.
