I'm sure I've listened to some of those. I remember not liking the music but the mixes were fully on point. I'll suggest someone was critiquing the music and not the mix.I've no idea.
Just forgot to mention him in my post.
His Opeth - Deliverance 5.1 mix is quite good and the latest Pineapple Thief album too.
He uses the rears in most of his live mixes for instruments. What I like!
