I'm a little late chiming in on this thread, but I feel I should contribute to the discussion. I've been a musician nearly all my life and I have been following Steven Wilson's catalog since I first heard him with Porcupine Tree on "In Absentia" in 2002. For being a self-taught engineer and producer, he really does have a great ear for proper mixing and dynamic range, not to mention an excellent musician at setting the mood of the music. It's not very complex at all, but the layering concepts and atmospheres he puts down make up for the lack of technical ability. I know he despises the prog label he has been given, which is nothing like alternative and has been quite healthy since the 1990's, but he has fallen into that genre, which I listen to almost exclusively. I have a great deal of respect for him coming in as a late bloomer of sorts in the music industry and his popularity seems to be increasing. I sure could use his expertise mixing my music I've recorded on the computer. Hand Cannot Erase is an awesome mix. The "Regret #9" guitar solo is one of the best I've ever heard. I apologize if that was a bit long-winded.
