Black Mass Of Absu has been played on NTS shows including Crypt of the Wizard, with Trudging To Calvary first played on 6 January 2020.

Black Mass of Absu was headed by a mysterious figure named "Mr. Ski Mask". He was somewhat known in the more obscure noisecore/industrial scene for his band Ostomy; he also has a metal project called Towpath and is somewhat well known in New York state for his public access program, Thunderbird Theatre.

The other band members are unknown, though, and it's unknown which persona Mr. Ski Mask assumes in Black Mass of Absu.
