Release date: May 2013
Altered State is the second studio album by British progressive metal band TesseracT, released on May 27, 2013 through Century Media. Altered State was produced, mixed, mastered and engineered by Tesseract guitarist, Acle Kahney, assisted by bassist, Amos Williams at Acle's 4D Sounds studio, and marks the first full release with new vocalist, Ashe O'Hara, and to consist of wholly clean vocals.
Divided into four movements: Of Matter, Of Mind, Of Reality and Of Energy, 'Altered State' represents the transformations that TesseracT has gone through over the past few years. The Law of Conservation of Energy states that: in a closed system energy is conserved, nothing is lost; it merely changes from one state to another.
