TesseracT

England's TesseracT emerged as an early innovator within today's progressive metal landscape, merging technical precision with conceptual depth across expansive yet precisely structured releases. After circulating several demos and EPs, the group delivered its first full-length recording, One, during 2011. Commercial breakthrough arrived four years later when Polaris entered both the U.K. and U.S. charts; the same focused intensity carried into the well-received Sonder in 2018 and the 2023 release War of Being.

Guitarist Acle Kahney launched the project in 2003 while still performing with Mikaw Barish, initially as a solo vehicle that later embraced the djent approach—tight, palm-muted riffs whose name traces to Meshuggah's Fredrik Thordendal. The Concealing Fate EP appeared in 2010, One followed in 2011, and the Perspective EP surfaced the next year, containing a version of Jeff Buckley's "Dream Brother." Century Media issued the second studio album, Altered State, in 2013. Daniel Tomkins, present on the earliest EP and album, rejoined for the third long-player, Polaris, after two interim vocalists; K-Scope released that record in late summer 2015. Ahead of a North American run supporting Gojira in autumn 2016, the band reissued Polaris as a two-disc set whose bonus disc, Errai, contained reworked versions of "Survival," "Cages," "Tourniquet," and "Seven Names." A standalone single, "Smile," arrived in summer 2017.

In early 2018 TesseracT confirmed Sonder for April. Recording took place at 4D Sounds, Celestial Sounds, and Project Studios in the U.K., with engineering by the band and Aiden O'Brien and mastering handled by Acle Kahney. The album fused the abrasive edge of One, the progressive atmospherics of Altered State, and the melodic clarity of Polaris. February's advance single "Luminary" was introduced by Tomkins as "conceptually exploring a deep and devouring sense of insignificance, which ties into the overall theme and meaning behind Sonder," and was paired with an extended reworking of "Smile." A limited deluxe edition added a 360-degree binaural mix created by Klang.

After Sonder, Tomkins pursued solo work, issuing Castles in 2019 and Ruins in 2020. Late 2020 saw TesseracT reconvene—minus drummer Jay Postones, who remained in COVID-19 isolation—for an online cinematic performance titled Portals that revisited earlier material across more than two hours; audio and video editions followed in 2021. The two-track Regrowth EP, intended to benefit Ukraine, emerged in 2022, while the expansive dystopian concept album War of Being arrived in 2023. Self-produced by the band alongside Peter Miles (Architects, Sylosis) and centered on inter-dimensional politics and socio-economic tensions, the record was accompanied by a single-player VR sci-fi adventure game.
