UMUR "Resuscitation of Evilness" is a demo cassette tape by Finnish death metal act Convulse. The demo was released in November 1990 and it is the only official demo by the band. Convulse formed in 1988 under the S.D.S. monicker and originally played speed metal, but they changed their name to Convulse in 1990 and their sound with it. They released a couple of demos under the S.D.S. name, so while it says "Demo III" on the cassette inlay, "Resuscitation of Evilness" is the only official demo released under the Convulse monicker. "Resuscitation of Evilness" led to Convulse being signed to Thrash Records for the release of the band´s debut full-length studio album "World Without God" from July 1991.

"Resuscitation of Evilness" features 4 tracks and a full playing time of 15:12 minutes. All 4 tracks would be re-recorded and included on "World Without God (1991)". These early demo versions are worth a listen too though, and the material on "Resuscitation of Evilness" is generally a good quality example of early 90s Scandinavian death metal. The music is both well played and well composed, featuring tempo changes, quality lead work, powerful (yet slightly one-dimensional) growling vocals, and a high level of brutality and loads of raw death metal riffing. It´s raw, it´s brutal, and it features the right gloomy atmosphere. Considering that "Resuscitation of Evilness" is a death metal demo from the early 90s, the sound quality is actually pretty high. It´s definitely in the better end of demo sound productions from those days.

So upon conclusion "Resuscitation of Evilness" is a good quality first release by Convulse. The material is not the most unique sounding for the style, but Convulse do what they do, with both great conviction and reasonably good playing skills. The growling vocals are also delivered with the right attitude and sound, so a 3.5 star (70%) rating is deserved.
