I definitely disagree. The fact that Deliverance is a tad heavier than most other Opeth albums definitely doesn't mean it's standard death metal. I personally don't like pure death metal at all, but Deliverance is not only my third favourite Opeth album, but probably one of my favourite albums of all time. Of course, you are the one who decides if you like it or not, but I just don't think me7's description does the album any justice. I would rather call it a darker, more "focused" version of the BWP sound. If you enjoy BWP (and you seem to enjoy it), there is a pretty big chance you will like Deliverance as well. If BWP wasn't such an important album for me for personal reasons, I would even rank Deliverance over it. So definitely check it out, if you don't like it, okay, but at least give it a serious try. Or more than one. It took me a coupe of weeks to really get into it, especially Wreath was just way to different from the Opeth material I had heard before, but once it clicked, it was phenomenal.
