I still don't recognise any of the vocals sung on Deliver Us as 'clean vocals'. They may not be screams or growls, but they are far from what i consider 'cleans'. Clean vocals are the title track of Come Clarity and chorus of Reflect the Storm and Crawl through Knives. In fact i don't consider there to be any clean vocals on ASOP at all, except for the spoken word-esque The Chosen Pessimist.
The vocals on Deliver Us are more like the half-scream, half-shouts similar to those found on ASOP. But way better, more gruff and the notes are held much longer (sounds like Anders has been giving his lungs a workout, perhaps the vocal training we heard about previously?). Not only this but the lyrics are much more clever, meaningful and memorable, bringing to mind the days of Clayman, Reroute to Remain and STYE.
Also: i saw the tracklisting and the corresponding song lengths on Wikipedia and i am ecstatic that there are multiple songs running over 5 minutes long! Never mind that fact that most are over 3 minutes long! This means more of everything crammed into each song and more In Flames!
