Errai features four re-worked tracks from the band s critically acclaimed 2015 studio album Polaris Survival, Cages, Tourniquet and Seven Names. The tracks have been re-imagined by the band s long time live producer and sound engineer Aidan O'Brien.
TesseracT vocalist Dan Tompkins comments "It's been fantastic to re-visit & re-work the vocals to some of the Polaris tracks from a different angle and with the benefit of time and space. The normal process of writing TesseracT songs starts with the creation of the music followed by the lyrical content; this time Acle and Aidan have stripped away the music and recreated the songs based around the vocals. As a result this has allowed much more breathing space between both and also highlighted much more detail in the performance".
Along with the new song interpretations the cover art for Errai sees the Polaris artwork having a 2016 make-over by artist Dan Mumford.
