The way that chris' vocals are blended into the mix production wise to me is very reminiscent to radiohead's work in "Kid A" and "Amnesiac". Now I know it's stereotypical to compare the two but to me this is an obvious comparison, and I think Coldplay will definitely benefit from it. It shows they're willing to experiment while sticking to their roots of pop anthems and ballads, and their latest 2 efforts have thoroughly impressed me in quality of everything from vocals-songwriting-instrumentation-experimentation-production and I expect big things from the album, particularly from a critical standpoint.
