UMUR "Landfill Breastmilk Beast" is an EP release by US post black metal act Cobalt. The EP was released through Profound Lore Records in June 2008.

The EP consists of three tracks and features a total playing time of 44 minutes. The first two tracks "Stomach" and "Extinction" are in the post black metal style of the band´s last album "Eater of Birds (2007)" while the last track, the 29:31 minutes long "Ritual Use of Fire" is a long ambient sound experimental piece. The latter was recorded solely by vocalist/ guitarist Phil McSorley. While the two first tracks are very enjoyable, aggressive and well composed, "Ritual Use of Fire" is overall of a slightly more questionable quality. Almost 30 minutes of ambient experimental sounds, is about 25 minutes too long. It´s of course an aquired taste if music like this is something you´ll be able to appreciate, but just be aware that you shouldn´t expect anything remotely metal oriented for 30 out of the 44 minutes this EP lasts. The "Ritual Use of Fire" concept was also used on "Eater of Birds (2007)" albeit in much smaller doses and on that album used as effective breathers between the harsh black metal tracks.

The sound production is professional and powerful, and suits the music well. Upon conclusion "Landfill Breastmilk Beast" started out as a 3.5 star (70%) release but after listening to "Ritual Use of Fire" my rating has dropped to a 2 star (40%) rating. Maybe other listeners can enjoy this piece of ambient sound experimentation, but honestly I call it a bad excuse for not having enough proper material to put on the EP. It could have been so good but ended up a disappointment.
