So if you like your prog rock (floyd, early genesis, Elp, jethro tull), then the new Opeth album Sourcress is for you. Listened to it a few times on splotify and really like it. Their most prog album so far, sits in the middle between the prog/death metal blackwater park phase and the acoustic/folk Heritage album. Lots of references to floyd but also bring in some world influences. A jolly good listen and can't wait to see them in November at Wembley.
