UMUR "Metamorphosis" is the fourth demo recording by US, Tampa, Florida based death metal act Brutality (the fifth if you count the 1987 demo by pre-Brutality act Abomination). It´s the successor to the 1989/1990 "Dimension Demented" demo. The demo was independently released and sold an incredible 5.000 copies. The demo was partially financed and distribued by Wild Rags Records though, which is why it´s sometimes counted as a label release.

Stylistically this is the sound of Brutality coming into their own and finding their sound. They starting out playing a raw and primitive thrash/speed metal style, and ended up playing an aggressive and brutal crossover thrash metal style on "Dimension Demented", but have now finally landed in the death metal camp. Their music still features quite a few thrash metal styled riffs and rhythms, but this is predominantly brutal, dark, and heavy death metal. None of the three tracks from the 12:38 minutes long demo would be included on the band´s 1993 debut full-length studio album "Screams of Anguish", but "Mausoleum of Infringing Evil" would be re-arranged and become "Septicemic Plague", which is featured on the debut album.

The material isn´t as well rounded and consistent in quality as what Brutality would produce on their full-length studio albums, but that´s to be expected from a demo recording, but when that is said, "Metamorphosis" is still a quality US death metal demo by Brutality, and a 3 - 3.5 star (65%) rating is warranted.
