UMUR "Metamorphosis / Dimension Demented" is a compilation release by US, Tampa, Florida based death metal act Brutality. The compilation was released through Mega Rabbit Recordings in 2002. The official nature of the release is disputed, and some sources says it´s a bootleg release. The compilation is released through the label of original Brutality lead vocalist/guitarist Larry Sapp (now Raine von Kiszka), so in that respect it can´t be counted as a bootleg.

The compilation features the material from the 1989 "Dimension Demented" demo and the 1991 "Metamorphosis" demo. The material from the latter is actually featured twice. The original demo cassette tape featured the same three tracks on both sides of the cassette tape, and for some reason it was decided that both Side A and Side B of the original cassette tape should be included on this compilation (which strengthens the suspicion that this is actually a bootleg). The compilation opens with the three tracks from the "Metamorphosis" demo in one 12:45 minutes long track, which is followed by the three individual tracks from the demo. It´s quite confusing and pretty unprofessional to release something like that, but that´s the reality of this compilation.

The tracks from "Metamorphosis" are followed by the eight tracks from the "Dimension Demented" demo. While the material from the "Metamorphosis" is death metal with some traces of thrash metal, the material from "Dimension Demented" is brutal, heavy (and occasionally fast-paced) crossover thrash metal. There´s not much connection between the material from the two demos other than it´s the same band who released them, but that´s about it. They could easily have been released by two completely different artists, and you wouldn´t have questioned it. The quality of the material is relatively high ("Metamorphosis" is of a better quality than "Dimension Demented"), but as a compilation release there are several things which do not work. The double inclusion of the material from "Metamorphosis" is more or less unforgivable, and it´s also a bit weird to listen to a release featuring two completely different music styles. Still there is enough quality here to warrant a 3 star (60%) rating.
