Sound — 8
Another in an increasingly long line of "progressive deathcore/metalcore" bands, Sentinel are at least doing it well. In a flooded scene of once unique sounds, Sentinel do not bring much new to the table, but they don't have to. Their blend of Misery Signals-esque melodies, At The Gates riffage and Meshuggah styled breakdowns, all in a neat deathcore shell, works extremely well. The opening track sums this up quite well, as it begins with out-and-out blast beats and chugging riffs, and by the end, has worked it's way through a few riffs that would make In Flames proud, before ending in a beautifully constructed outro using harmonised guitar layering to great effect. The rest of the demo follows the tried-and-trued pattern neatly, and nothing offensive is dropped into the mix to really shake it up, but at the end of the day, there's only so many chords, and it's what you do with them that counts. The production deserves notice, especially since the very notion of a "demo" denotes less than admirable quality, Sentinel do not adhere to that rule. Everything fits quite neatly into the mix, and a good guitar tone will always help bring a riff to it's maximum potential.

The vocals are nothing remarkable, but they fit the music nicely and remind me of a 3750-era Vincent Bennett (The Acacia Strain). I will give the band particular praise for not succumbing to the "all epic chorus' must have clean vocals" idea that seems to be spreading throughout the deathcore populace, as he has enough power in his harsh exhales to make the sections work more than adequately.
Overall Impression — 7
As I said earlier, don't expect anything too revolutionary, but for a demo, this band has definitely found a nice little niche to sit in, and if they can expand upon it, and turn it into something with a bit more character to it, I can see a respectable future for this band.
