UMUR "Demiurge of the Void" is the 3rd full-length studio album by Polish death metal act Deivos. The album was released through Unique Leader Records in September 2011. It´s the successor to "Gospel of Maggots" from 2010. Since the predecessor bassist/vocalist Jarosław Pieńkoś has left and has been replaced by bassist Kamil Stadnicki and lead vocalist Hubert Banach (also known under his charming stage name Angelfuck).

"Demiurge of the Void" continues the brutal technical death metal style of its direct predecessor but as a result of the production choices, it´s a more raw and filthy sounding release than "Gospel of Maggots (2010)". It´s incredibly intense music with a very high brutality factor. Deep unintelligble growling vocals, fast precision drumming (with quite creative use of cymbals), and fast and brutal riffs are some of the ingredients of the band´s sound. In many ways the epitome of the brutal technical death metal style, but Deivos generally have a little more to offer than your average band in the genre. The many tempo changes, use of brutal grooves, and especially the adventurous drumming, make Deivos stand out a little.

To most ears "Demiurge of the Void" will probably sound like most other brutal technical death metal releases though, but it is definitely an album where it´s worth investigating the details. While Deivos typically shine when they try something a little different from the norm of the genre, there are also sections on the album, which are very standard for the genre. Both in terms of songwriting ideas and quality. One of those features are the vocals, which are as standard as they get in this genre. They are relatively well performed, but they add very little to the music and more distinct sounding growling vocals, could pretty surely have elevated the album to a higher state. A 3.5 star (70%) rating is deserved.
