I think In Absentia is PT at their peak.   There's a couple of tunes in the middle I sometimes skip, but the rest of it is flawless, and endlessly exciting.  I also really like Lightbulb Sun, probably a very close 2nd.

Deadwing is my favourite PT album. Its a bit more metal sounding than the others. Fear Of A Blank Planet gets load of plaudits understandably and has the required intricacy to please the average prog fan. In Absentia has perhaps the best songs while of the nineties albums I prefer Up The Downstair over The Sky Moves Sideways. Signify was the transition album as Wilson created a proper band to move forwards with. That and Stupid Dream solidfied the style and approach that we now recognise.

Solo wise Grace For Drowning was the album of 2011 by my reckoning. Good to see SW expressing himself fully. The Incident was perhaps an indication that the band was getting a bit stale. Will be interesting to see what the future brings for SW. Maybe he might dip his toe a bit in the 'retro' scene?

I'm going go out on a limb here and say that Deadwing is a sleeper. Really, I just can't get into that album at all. Arriving Somewhere just goes on for way too long, despite it being a great track nonetheless - the atmosphere that is created is incredible. The title track is rather good, except I'm not too keen on the Mike Portnoy esque vocals in the verses. 
Lazarus is probably my most played song from the album - very beautiful, warm. Everything else though, especially the singles (i.e. Halo), loses my interest. I know I'll probably get a lot of flack for this. That being said though, I love PT and Steven Wilson solo material. The guy is one of my favorite songwriters on the past century. He has a very unique approach to crafting his songs and an eclectic, musical mindset - one of a kind. The Sky Moves Sideways and Fear Of A Blank Planet are my two favourite PT albums. The concept of FOABP is something I can relate to and reflect upon.

Fear of a Blank Planet is my favorite, it has a great mixture of moods. Also it is accessible and interesting at the same time. Great drumming as well!

I was gonna ask why he  needed two threads./

Originally posted by Mirror Image I turned up nothing about a topic devoted to Porcupine Tree or Steven Wilson that wasn't a poll in PA's search engine, so here's a thread we all can use to appreciate the music of PT/Steven Wilson.

so...

What do you mean by most succesfull?
In sales? In fame? Or which one is our favorite?
In any case I will write my opinion and we'll see...
I believe both in sales and fame are 'Lightbulb Sun' and 'In Absentia'
Mine most beloved ones are 'The sky moves sideways', 'Lightbulb Sun' and a liiitle behind comes 'In Absentia'

ah, ok. Thank you! 
Then I'll go for 'In Absentia' I think...
Although I'm not familiar with their latest 1-2 releases...

I suspect I may be not a hard-core PT admirer, because I don't care much for their pre-Harrison output. The earlier PT were profound and inspired, but a little too experimental and not sufficiently mature (to my ears). Speaking of the lyrics, the weirdness sometimes outweighed the wit, I'm afraid. 

Therefore, I think In Absentia and Deadwing were in a way what Rubber Soul and Revolver had been for the Beatles, a spectacular  transition from a "curiosity" into a "unique phenomenon". Thus, FOABP became their Sgt Pepper and beyond. There is simply no other album that could be compared to FOABP in terms of contents, execution, exquisite musicianship and extraordinary engineering. In my book, FOABP is worth as much as all of the Pink Floyd, King Crimson and Yes output in the early 1970's. . 

The Incident, while an excellent album in its own right, wasn't as fundamental and majestic as FOABP ('Let It Be?')

I also think that Wilson's recent solo albums again shifted towards more experimental contents (the absence of Gavin Harrison?), and I have no place in my heart for IEM, No-Man, Bass Communion, let alone Blackfield and Storm Corrosion.
