UMUR "Deep Deep Down They Sleep" is an EP release by German death metal act Sulphur Aeon. The EP was released through Imperium Productions in May 2012. It´s the band´s first official label release. Sulphur Aeon were formed in 2010 and released the "Sulphur Phalms" demo the same year, before releasing this EP. None of the material from the demo is featured on "Deep Deep Down They Sleep".

"Deep Deep Down They Sleep" features 2 tracks, and a full playing time of 8:42 minutes. Both tracks are in a technically well played, brutal, and atmospheric death metal style. It can sound quite chaotic because lots of things happen all the time in the music, but Sulphur Aeon are both skilled musicians and composers, and the chaos is cleverly structured.

The sound production is professional, powerful, and pretty raw, which suits the music perfectly. So it´s obvious that Sulphur Aeon have a lot to offer the listener. The tracks could have been slightly more catchy, but that´s a slight issue, and considering it´s the band´s first official label release it´s actually quite impressive. A 3.5 star (70%) rating is deserved.

Sea Whisperer Sulphur Aeon is a German Death Metal band, founded in 2010. “Deep Deep Down They Sleep” is their first EP, which was released in 2012. Lyrics of their songs are based on H.P. Lovecraft’s works, mainly on Cthulhu mythos.

From the first seconds of the title track listener is greeted by fast and intense Death/Black metal in vein of early Behemoth and Morbid Angel. Guitars create an impenetrable wall of sound with tremolo riffs upon it, drums provide thunderous blast beats as well as more intricate parts in slower fragments and vocals by Martin Hellion are powerful and furious. Yet another important part of the bands’ sound is production – it is rough and a bit muddy, and its contribution to the atmosphere of this EP is immense. Slightly hissing guitar sound along with crushing drums makes you think about roaring sea, in whose unfathomable depths ancient horrors from beyond the stars are sleeping.

Despite of overall brutality of music here, there are plenty of simple yet hauntingly beautiful guitar lines, providing a necessary contrast with rhythm parts. In the second track they also act as small leitmotivs: a pulsating two-note pattern with a periodic change in pitch is all this band needs to create ominous atmosphere.

Summary: a very solid work, skillfully capturing the mood of Lovecraft’s writings. This record is only about 9 minutes long, but it’s packed with amount of fury and raw power worthy of full-length album.
