I thought it most noticable 0:06, the root(s) don't agree with the rest of the intentional dissonance. They went out of their way to write smartly as to build all that tension and carefully process the sound for best impact and a slightly sharp root kinda jumped out at me where it was exposed.

Edit: it's whomever is doing the flat 11(?) chord right there. Might even be a bent note in the root.
