Heady Mental is the perfect title for the third Mammatus album, for it rests heavily in the moldy caverns of heavy metal history, but doesn't get too comfortable there. It quickly shows it's true colors: This is music for flight, music for the sky, and music for the things that lay beyond. These men are searching for the source through sound. Repetitions of themes with variants are spread over four separate songs that act as a whole. This record functions as a soundtrack to the Mammatus Brain. Heavy/Airy, Earth/Sky, Man/Creator, Complete and Grok'd.
