UMUR "13" is the 8th full-length studio album by US, Florida based death metal act Six Feet Under. The album was released through Metal Blade Records in March 2005, only about 6 months after the release of it´s predecessor "Graveyard Classics 2" from October 2004. "Graveyard Classics 2" was not an album featuring new original material though, but instead Six Feet Under playing the entire "Back in Black (1980)" album by AC/DC. So "13" is the first release with new original material since "Bringer of Blood" from 2003.

Stylistically the material on "13" is unmistakably the sound of Six Feet Under. Predominantly simple and mid-paced old school death metal with some heavy grooves and a brutal growling (and occasionally higher pitched screaming) Chris Barnes in front. If you are familiar with the preceding releases in the band´s discography you´ll find few surprises here. The quality is relatively high throughout though, and most tracks feature memorable riffs, rhythms, or vocal phrases. As usual the lyrics are about violence, death, and gore.

"13" features a well sounding production job, the band are well playing, and as written above the material are generally well written and relatively memorable too, so upon conclusion "13" is another quality death metal release from Six Feet Under and fans of the band and old school death metal in general should find a lot to enjoy here. It´s not that it´s a revolution, but it´s a solid release and a 3 - 3.5 star (65%) rating is deserved.
