The pioneers of an ever-evolving metal scene, Tesseract, released their fourth studio album entitled Sonder in April 2018, following 2015's worldwide acclaimed Polaris. Originally formed as a studio project by guitarist Acle Kahney, Tesseract are a band full of melody, dynamics and groove, they sit outside the bounds of any genre specificity to truly create a sound that has always been pioneering and creative; an unstoppable force of off-kilter riffs, soaring melodies and disorientating atmospherics. Prior to Sonder, the band's vision quickly translated to success, with a collective 100,000 sales in North America alone. Polaris reached Billboard's #10 (Hard Rock) & #57 (Current Albums) charts and #9 in the UK (Indie Albums) and #7 (Rock and Metal), and have seen continued support from worldwide press. Having found a new creative energy after reuniting with original singer Dan Tompkins, the band's output changed in 2015 with the opus Polaris; an undoubted evolution from Altered State and features skilful experimentation with sounds and tones, plus a deeper exploration of the core attributes that define Tesseract's trademark sound.
