Opeth - "Death metal sound is over"

I noticed some of you were discussing Åkerfeldt's (in a bad way) deteriorating growls. He said in a recent interview it was caused by the new in-ear monitors he's been using on stage. He heard his voice in an unfamiliar way with the speakers being so close to his ears, leading to him compensating with straining himself. That's why he's sounded so bad, and why he got a sore throat after some nights. Or at least that's what he says. And the new Opeth song is tits, if you hadn't noticed.
