There was a period full of "brutal" bands (how I hate saying "brutal"!): a lot of bands playing that kind of death metal (born in US) based only on piggy style vocals and artificial harmonics.
Fortunately HEADLESS are not sons of that wave. Their biography claims Florida influence, of course, but I can see a lot of other influences. Early Sinister but also Krisiun (for the blastbeat style), Incantation and early Cannibal Corpse, came to my mind! Album atmosphere is sick and dark... The growl, cavernous and deep, is never excessively guttural and it filled well in every part of the songs. Blastbeat is devastating and barbaric, never technically precise, and alternates with powerful old school tempos. There are also slow parts that give to the songs a feeling of obscure malignity. Guitars propone a good riffing, violent and insane, and bass guitar sometimes rises up creating an horrorific and sick sound.
For example in the second track "Xipe Totec", there's a long slow part corrupted by dissonant guitars and obsessive bass riffs. Great tempo changes in the third track "Elimination Way": after an heavy start, a solo bass introduces a furious blastbeat followed by an infinite serie of virtuos passages. All the tracks in general got some surprises in the structure so we never get bored! I conclude writing about the cutting evil riffs of "Tezcatlipoca", attacking in Slayer style mark the most intense part of the cd in an esotic Nile-style feeling. A good work, well recorded and played.
Genuine death metal able to give a right dose of brutality and sickness!
