Glad this band are more consistent lately with the last few releases.
To me;
Ember to Inferno was ok but lacked polish and was clearly a young band finding their feet;
Ascendancy was epic, one of the best "pure" metalcore albums. Defined my teens, still love it;
Crusade I liked more than most as I'm big on thrash, but it is quite tame and cheesy at times;
Shogun is their masterpiece. Great album from start to finish, took the best parts of Ascendancy and Crusade and blended them with progressive, interesting songwriting;
In Waves was initially a big dissapointment after Shogun. Seemed like such a big step back. Very straightforward metalcore, bland songwriting. It's ok but I don't revisit it often;
Vengeance Falls is a big pile of meh to me, apart from the last 2 songs. Lacks dynamics, and sounds like Disturbed
Silence in the Snow was also mediocre and fairly boring to me;
Sin was a big step up after the previous 3. Much more interesting songwriting, brought the grit and dynamics back. Great album, revisit it often;
What the Dead Men Say followed the same path as Sin, but slightly less inspired. Still good though.
New album is great so far, last the last 2. Not sure if it's as good as Sin yet, but it's up there.
