King Crimson

+1 on Thrak don’t overlook it and most any live KC album is worth the money.

....on the way 200g court vinyl mixed by Fripp Wilson. 

Late King Crimson alboms are really well recorded you may fully enjoy them. Among their early albums ones with Greg Lake i like more. I love to hear his voice.

And Emerson, Lake & Palmer is my number one rock group - three super genius musicians together (together with Led Zeppelin in another number one branch). Even their classical early alboms are quite well recorded (except Brain Salad Surgery that, for me, sounds odd - i don't mean the music of course).

That's funny about ELP. They were also my favorite group until I saw them in West Palm Beach on their Brain Salad Surgery Tour. The Leaky Tepee (WPB Auditorium). No reserved seating, it was a mad dash and I was was right up front, essentially first row...no emotion, Greg and Keith just chewed gum and went through the motions. Fail...I dropped them like a rock.

Understand that I’ve seen the YouTube videos of ELP concerts from earlier years and they were great.(Keith destroying the organ.etc.) I’m specifically talking about the later BSS Tour. That was my first live experience with them and their boredom was palpable. And it turned me off from them forever.
