UMUR "Blood-Nurtured Nature" is the debut full-length studio album by Belgian/US death metal act Macabra. The album was released through metalhit.com in February 2012, and is available in both CD format and in digital format. Macabra were formed in 2011 and consist of Mark Riddick (all instruments), and Adrien "Liquifier" Weber (vocals).

The music on the album is old school death metal with unintelligible growling vocals and occasionally higher pitched aggressive snarling vocals. The concept is clear and there are very few moments of anything that breaks the boundaries of the old school death metal genre. The two guys in the band perform their parts relatively well, but none of them show any skills beyond what you´d expect on an album like this. The drumming might even be a little below standard.

The material on the 8 track, 35:20 minutes long album is decent enough while it plays, but it´s not exactly music you´ll be humming along to or remember much about when the album is done playing. Macabra knows all the right death metal tricks, but they have a very hard time coming up with memorable riffs or vocal phrases, and the whole thing quickly reeks mediocrity. Add to that a sound production which is just slightly below professional standards and "Blood-Nurtured Nature" does end up coming off a bit amaturish. It´s not bad as such, just very standard for the genre and a 2.5 - 3 star (55%) rating is warranted.
