I give this DVD ***** because I saw it when it was first shown as a movie in theatres in the mid 1970's.  I am very happy that someone choose to preserve this gem. I am a progressive/progressive metal aficionado from before YES & ELP. "In the Court of the Crimson King" is probably the first recognized progressive album/ group and it still is alive and well today. King Crimson lost Greg Lake to ELP and gained Bill Bruford from YES. Bill Bruford did play on some of songs on the Yessongs album, but Alan White replaced him during the Yessong tour(s)and played drums & percussion on the Yessong movie, which was from a performance recorded during the tour(s).
