I have all regular studio albums from Porcupine Tree, Blackfeld and Steven Wilson. But that is only a small range, of what he has released, because - as someone on the old forum put it - he is the master of music and the master of the special edition.
I got to know PT in the year 2000, when there was a big hype around the band on the old German Marillion forum. I saw PT live in Dresden early in 2001 at the Star Club with only around 30 people in the audience. In May of the same year, I saw the band again as a support act for Marillion in Cologne. Steven Wilson returned to Dresden during the Raven - Tour. This time he played a bigger venue, which was sold out. He will return here in July and do an open air gig.
The early albums of Porcupine Tree are pretty much Pink Floyd influenced, with some ambient influences as well (Voyage 34). For me the band really kicked off with Signify and the live album Coma Divine from that tour. Signify, Stupid Dream and Lightbulb Sun are my favourites. On these albums PT had grown together as a band and here they developed their wonderful and unique style, for which I learned to love them. The albums that followed are in a heavier vein, but still are great. A special mention goes to Deadwing, which includes the incredible "Arriving Somewhere But Not Here" and other gems. The CD-set "Octane Twisted" includes a dvd of a live rendition of the complete "Incident" - suite.
Steven Wilson`s solo work is varying quite a bit. Some of his solo albums are very much in the vein of PT, especially The Raven, That Refused To Sing and Hand. Cannot. Erase (both absolutely awesome albums). Grace For Drowning and Insurgentes also include some jazzy, experimental elements, which might not be liked by everyone. The most remarkable track in that respect is Raider II. There is a fantastic live dvd from the Grace For Drowning tour, called Get What You Deserve. This is really highly recommendable.
To The Bone is newest album, it belongs to my top five of all SW/PT stuff.
