UMUR "Demo 1990" (or just "1990" as it says on the cover of the cassette tape demo) is the third and last demo recording by US, Buffalo, New York based thrash/death metal act Malevolent Creation. The demo was released in April 1990 and was originally limited to 1.000 cassette tape copies. It was on the grounds of this demo that Malevolent Creation were signed by Roadrunner Records for the release of their 1991 debut full-length studio album "The Ten Commandments".

The three tracks on the 11:41 minutes long demo were recorded at Morrisound Recording, Tampa, Florida, and they feature a professional, powerful, and brutal sounding production, which helps make the tracks shine. All three tracks from the demo would be re-recorded and included on "The Ten Commandments" (1991), but actually appear here in versions which are more or less identical to the album versions (the guitar solos are sligthly different). Compared to the first two demos, the music has become even faster, heavier, more brutal, and most important of all lead vocalist Brett Hoffmann has developed his vocal style to become more brutal. He is still not a traditional death metal growler, but instead employs a semi-growling snarling vocal style which is probably still closer to thrash metal style vocals, but slightly more brutal than the average thrash metal singer´s vocal repertoire.

Upon conclusion this is an absolutely killer demo recording, which in some ways is even more powerful, raw, and savage than the debut album featuring the same tracks. A 4 star (80%) rating is fully deserved. This is one of the most well sounding death/thrash metal demos of the era (along with the Demolition Hammer´s 1989 "Necrology" demo).
