Great, glad I am not the only one then Roger!
I also love the electric guitar solos prevalent in this genre. There's a great such solo in Black Light Machine just after the wonderful arppegiator effects at 2:56. What a classic electric solo - again, this album is just the best.
I've done one little piece of my own that isn't quite progressive rock génre - but is an electric guitar solo using a similar guitar sound to that heard here. If it's OK to post a link to this I am happy to, here goes...
