Query: Deadwing is missing some tension

Deadwing is not a bad album at all. The first time I was exposed to it, I was somewhat disappointed. It took me a very long time to appreciate it. Compared to In Absentia, Stupid Dream, Signify and Lightbulb Sun and other PT albums Deadwing seems flat and uninspired. Comparing Deadwing to the entire field of music put out at roughly the same time is easy. Deadwing is clearly better.With Deadwing, I miss the beautiful fusion of very hard rock and light airy music playing off each other in perfect harmony on so many other PT albums. Deadwing seems a bit flat to me. Deadwing should not be the first Porcupine Tree album for new Porcupine Tree fans to listen to, because that would give the wrong first impression of the band.The point is, Porcupine Tree has put out much better stuff than Deadwing. If Deadwing is all you've heard from Procupine Tree, I have a piece of advice for you. Backlog! You won't be disappointed!
