*Calm Black Water* is an album by the American band REZN, released on LP in 2018. The album belongs to the psychedelic doom metal genre, in which heavy, ponderous riffs combine with dreamy, atmospheric layers of sound. On this record, REZN constructs a compelling sonic world full of slow tempo shifts and hypnotic guitar textures, underpinned by deep basslines and powerful drums. The sound of Calm Black Water is characterised by a combination of stoner rock influences and psych-rock elements, with the band leaving room for both heaviness and subtle atmosphere. The production of the LP is imbued with a dark depth, making the listening experience feel both meditative and oppressive. The build-up of musical tension and the use of dynamics ensure that the album maintains a constant underlying tension, fuelled by both recurring melodies and complex layers of sound. The album was released on vinyl in various editions, including a crystal-clear, blue-and-white marbled pressing, and has since its initial release gained a strong cult following amongst fans of the genre. *Calm Black Water* is regarded as one of the highlights of the contemporary psychedelic doom scene.
