@paulg1966 - good post! To me and many others, Steven Wilson is kind of the King of 21st Century prog rock - just check out the massive amount of music he's put out both under his own name and with his band Porcupine Tree. Great with sound as well, hence those Tull remasters you mentioned; he first got big in the re-master thing with King Crimson; he's re-mastered a great many of their albums.
I like Phil Collins as a singer - he does singing with Peter on a number of Genesis songs, and their voices blend in so nicely together. But Phil was one of the greatest drummers ever - shame most of his fans probably don't know he played drums! And as I was saying earlier in the thread, I suggest you check out '9 Parts to the Wind' by Strange Days, if you haven't already!
And speaking of the darker side of prog rock, any fans here of Peter Hammill and Van der Graaf Generator??
