I was unfamiliar with this Texas-based musician, but Mortis is the work of one Zachary L. This is not to be confused with the Mortiis with 2 I's. The liner notes state that this release is based on the horror game Anatomy and the opening sample is from the game as well. This is a re-release/remaster of a old N0123NOISE track.
We begin with a slightly distorted voiceover on a PA system that suddenly ends, giving way to heavy rumbling drone and a quiet melancholy synth line. Crackling noise and the sounds of footsteps and pounding on a door break in occasionally. The sound of chimes echo in the distance. You get the sense that Mortis is trying to be creepy from the title alone, but they pull it off with aplomb. This is well constructed soundscapes of heavy drone and atmosphere that does a great job of evoking a dark night in an unfamiliar place. You're lost, and you could swear that you saw someone watching you before darting around the corner ahead. Nicely done. This disc weighs in at around 19 minutes.
