If you listen to blackwater park while looking in a mirror you hear a brutal version of harvest and an angelic version of the title track, then akerstash comes out of the mirror and gives you a bunch of flowers, they all have dead bees in them though, mirrors don't fuck around.
Sounds identical to Novembre - Nursery Rhyme, which was released 1996.
Coincidence? Perhaps, Opeth had quite a few songs really similar to others. Another example is Rapture - Two Dead Names (released 2002) Song: Opeth - In My Time of Need (2003).
Blackwater Park (the song) is perfected death metal. Not sure exactly what kind of genre this song could be put under, but I'm sure that this is about as good it could get. Pretty sure that's why Opeth has progressively become more and more prog rock (whatever you want to call Heritage), because they have damn near conquered a genre. This song is Opeth in pure acoustic form, and rivals Blackwater Park as a death metal counterpart.
Death Metal is not limited to growls, and Opeth is not limited to Death Metal. This song also shows that Opeth is capable of balancing aggressivity and calm in an album, which is perfect. Songs like Harvest by a band like Opeth is a proof of their proficient musicianship. Of course, not every one likes such songs.
I absolutely love the chorus. I love the verses also. The chorus is sung on another tone which I find richer and with some more variation as compared to the rather monotonous (monotonous does not mean boring), lamenting-like (and beautiful) verses.
