I can't believe that no one has posted anything about Steven Wilson yet... I think Steven Wilson is amazing, his music is very inspiring. I first got into his music last summer when my boyfriend gave me a Porcupine Tree cd, In Absentia. So beautiful, Collapse the Light Into Earth is my favorite, and I'm actually listening to it right now..
I would recommend buying Lightbulb Sun by Porcupine Tree to anyone who would like to experience Steven Wilson. Also, visit his myspace page, he has links to all of his other bands there...
