UMUR "Gangrene" is the 3rd full-length studio album by Swiss symphonic/progressive black metal act Mirrorthrone. The album was released through Red Stream, Inc. in April 2008. It´s the successor to "Carriers of Dust" from 2006. Mirrorthrone is a one-man act featuring Vladimir Cochet on bass, drum programming, guitars, keyboards, and vocals. Cochet formed Mirrorthrone in 2000 and released the debut full-length studio album "Of Wind and Weeping" in 2003. Cochet also releases albums under the Weeping Birth and Unholy Matrimony monickers.

Stylistically the material on the 6 track, 64:42 minutes long album continue the symphonic/progressive black metal style of "Carriers of Dust (2006)". Cochet is obviously classically trained and the compositions feature an omnipresence of classical piano and keyboard parts. Not completely unlike what some of the last Emperor albums sounded like. The drums are programmed and while they do feature an artificial digital sound, the actual drum programming is well done, and the programmed drums drive the music forward with the needed power. A human drummer would have been preferable but this is decent enough and doesn´t distract too much from the overall impression of the music. The vocals vary from snarling black metal type vocals, to clean vocals, to choirs, and there is generally good variation in the vocal department.

The tracks are generally very long, the shortest being 6:40 minutes long and the longest being 15:02 minutes long. They are structurally pretty complex and contain many different sections, atmospheres, and changes. A few more hooks to help tell the tracks apart would have been great, but it´s hard not to be impressed by the compositional skills at display here. The black metal parts are of the more polished kind, but that part of the music is perfectly designed to work with the many classical parts. So while I find "Gangrene" a more fascinating/intriguing release than an effectful and listenable ditto, my conclusive opinion is one of being mighty impressed by what I´m listening to. A 4 star (80%) rating is deserved.
