There are metal albums out there which strike you as unique/original/innovative/etc. (whether by way atmosphere, spirit, or something more objectively-observable such as song structure or the level of musicianship), but no matter how you many times you approach it, you can't find (or you hardly find) personal enjoyment in it. Name/Discuss them here. Here are some of mine... Gorguts- Obscura (Probably going to the case for many people; this re-defined what death metal instrumentation can be like. The abrasive atonality and the annoying 'desperate' vocals by Hurdle in some tracks prove to be drawbacks to my enjoyment, however. 'Clouded' is particularly one HELL of an endurance test. The odd/ironic thing is that I can see what a certain opinion is saying about the album in a review; it states "Contrary to popular opinion, I find Obscura to be hooky and catchy; not dense or overtly chaotic" [e.g. if Gorguts aficionados think about it, this is true for the track, 'Subtle Body', especially]. I do particularly enjoy tracks such as 'Earthly Love' and 'Sweet Silence', however.) Massacra- Final Holocaust (For the time, no band wrote constantly-evolving death/thrash riff structures quite like this. Unfortunately, the production values [along with other factors] fail to immerse me into the album) Emperor- In the Nightside Eclipse (For something this expansive, everything sounds so compressed. Additionally, much of the songwriting has a unappealing meandering nature to it. Still, this is their best album to me, and "Inno A Satana" is one of black metal's best closing tracks) Cadaver- In Pains (Inventive power-chord approaches; I've listened to it many times, but has done mostly nothing for me) Beherit- Drawing Down the Moon (Like Mystifier, one of the best uses of effect-laden vocals ever. Plus, some solid subtly-stimulating ambiance on tracks like 'Sadomatic Rites'. I'm hardly in the mood for the album these days though).
