As a longtime fan (since Blackwater Park came out) I am pretty happy with the new common ground Mikel found to please both OldPeth and NuPeth fans alike.
I agree that the last 4 albums were mostly forgettable, aside from a few songs a riffs.
My biggest gripe is how much stuff is packed into each song. I liked when Opeth songs were long cause they really let an idea sit and stay with you. It wasn’t overly repetitive, they always made the long sections (aside from a few choice selections) interesting even they repeated a riff for 2-3 minutes.
I will say that this album has some AWESOME grooves. All the more reason I wish they lasted longer. I feel like songs would be more memorable and distinct if they did.
Overall I’m really happy with the new compromise of sound. I know they don’t want to do the same thing over and over, and this is a happy medium that is a great step forward.
