I Wanna Point Out

One man is largely responsible for most of the post-hardcore/screamo/metalcore music we hear today. It's this guy: Kris Crummett.

I'd be able to tell you the numerous albums he's produced including:
All Alesana CDs
Catherine
Dance Gavin Dance
Emarosa
The Devil Wears Prada
Fear Before the March of Flames
