This is probably the best demo of the 2005. Take the energy of early Misery Index, the grind of Nasum, an excellent production (for and album, and even more for a demo!) and play it perfectly: you'll have this amazing Brutal Grind Assault, with 12 short and rageful tracks.
Nothing groundbreaking, nothing innovative, but a great riffing (it takes something from all the classical grindcore/death grind tradition, all mixed amazingly well: Terrorizer, Carcass, and on...) that will make you headbang from the beginning to the end.
Vocals vary from a growl a la Assuck to a screaming that reminds me a little of Brutal Truth, with the guy singing his balls off. The drum doesn't cover the other istruments (this release is produced better than Anatomy Is Destiny by Exhumed, I think), but blasts all the time relentless giving a great 'feeling' to the songs without being only "tatatatatatata" with useless blastbeats.
This could be the best album of the year. Is amazing that these guys produced and played such a great release as a demo: their future is bright.
