Jeez why does no-one like AILD? They have easily the best drummer and best guitarists (ignoring A.J. from THA, Adam Dutkiewicz from KSE, Matt Heafy from Trivium). The Vocalist is one of the better clean singers in metalcore, and the growler is probably the best aside from Jess Leach (killswitch), Phil Labonte (All That Remains).
Fixed. Though I'm sure I still missed a few.
Seriously, I have listened to a lot of AILD back in the day and never found them to be as good as most other bands that have been mentioned.
Adam from KSE being a better guitarist? I don't remember being blown away by any solos on their albums, and considering that he *produced* the two most recent AILD albums, and puts out KSE's worst album (the new self titled), well it doesn't really matter then. And okay I forgot Heafy.
Leach was great sure, but I'm talking current people - he burnt himself out. And Phil? Don't make me start, All That Remains have been a joke the past two albums.
You should listen to the two newest AILD albums if you haven't because they are light-years ahead than their old stuff.
On the subject of deathcore, I like a few black dahlia murder songs (vulgar picture, miasma) but that's it.
edit: and I disagree about them being better growlers actually - the AILD guy is the most diverse of any metalcore growler by far - the high screaming, the shouting and the low death, he's got it all covered (most notably in the 2010 album).
