I don't like throwing the term masterpiece around too often, and as someone said before, there really isn't even enough material here for it to stand as a "masterpiece." However, I think that if Mikael had spent, or had actually had more time to spend on writing and developing songs for this album, it easily could've been a masterpiece. If you read the studio diary for Deliverance/Damnation, he basically said he wrote most of this entire album while in the studio. It's incredible to me that it's even as good as it is, given the conditions of putting together and recording two albums worth of material at the same time - especially considering all the technical difficulties and pressure he was under during the hellish recording process for Deliverance/Damnation.
I don't know of any other band who could've pulled something like this off, and while I don't want it to seem like I'm making excuses, I really don't think it's fair to judge Damnation as an album completely by itself. It was originally intended to be released alongside Deliverance as a double-album, so I judge the two has one extremely diverse piece of work in two volumes. Given that, I still don't feel that either of them are stunning albums on their own and I think this experiment would've worked out better if they spent more time on each album, and not just recording ideas as they come and then seeing how they turn out.
There's certainly some weaker parts on both albums that don't really impress me as much as tracks on past albums, but there's still some mind blowing stuff here in my opinion. It's not quite as good overall as I would've liked, but certainly not below my expectations. Windowpane, Hope Leaves, Closure, To Rid the Disease, A Fair Judgement and Wreath are all consistently brilliant as far as I'm concerned and these releases are certainly not any indication of Mike losing his touch in the slightest. I just think he stretched himself a little thin with these recordings and maybe didn't have quite enough good material going into the process to make these albums really shine standing on their own.
I remember him making a post or comment or something in some interview about saving the stronger melodies for Damnation, and that's exactly what I'm talking about. He was probably coming up with loads of ideas in the studio, but making two different albums at the same time has got to be incredibly challenging if you don't have an abundance of material going into the studio. I just hope next time the whole process goes smoother and these guys get to relax a little and take their time making an epic, layered album like Still Life, but in whatever direction they want to take the music.
