Loved Prog. Love it again now. My sister bought Close to the Edge, and I heard Minstrel in the Gallery at a friend's house, that was it, I was hooked.
Tull, Gentle Giant, Yes, Focus, Supertramp, Moody Blues, Floyd, I played them all endlessly.
My interest waned a bit around 1978, got into new wave, pub-rock, blues..XTC and The Police were gods when I joined my first band, and prog didn't seem to chime with going to clubs and chasing girls.
Got back to it in the mid '80's when it was a nice alternative to the slick pop of the day.
My favourite proggers these days are Marillion. Since Fish left (they were really a Trespass era Genesis clone band then) they've ploughed their own furrow, and consistently come up with the most beautiful music.
Here's a good 'un;
