Nope, this would be a first for me.
Now, as for comparing Deadwing to In Absentia or even Lightbulb Sun, I will have to flat-out say Deadwing is my favourite album from Porcupine Tree. I feel it is quite a ways better than Lightbulb Sun but marginally better than In absentia (which overall, is a fantastic album.) The thing is about Deadwing, at least to me anyway, is that there isn't a particularly "bad" song that stands out on the album like on the previous one (ex. the creator or strip the soul.) This one from beginning to end blew me away. I just like the fact how metal-influenced the album is and features some kick-ass melodies.
