Tegmentum is a cosmic progressive metal project with producer Michael Ball on guitar, Chelsea Murphy (Dawn Of Ouroboros, Cailleach Calling) on vocals, Kenji Tsunami (Ontogeny, Narcotic Wasteland) on bass, and Andrew Baird (Fallujah) on drums. This project formed with the intent of crossing over progressive metal styles with more extreme elements typically found in techniical death metal. 'Evolvement' is an allegory for self-discovery that boldly explores an emotional spectrum of euphoric highs and very deep lows.
