Here are some great, new ELP videos on YouTube.
Tarkus in 1997 at Montreax
This is very much like the concert I saw at the Hi-Fi Buys amphitheatre here around that time. And, yep, the old Moog is still there! 8-)
This was the piece the opened with. Note that, in the middle, Tarkus transitions to Pictures at an Exhibition. I thought that was pretty cool.
Rehearsing Karn Evil 9
And more KE9 rehearsal
Wow! Studio footage of rehearsal, presumably during recording of KE9 on BSS (which was released in 1972 I believe).
The Barbarian
A at best fair copy of The Barbarian. This looks like it was videotaped from a TV screen. Still, it's from the early 70s.
Emerson on the Letterman 1986
Playing Coming to America, which was one of the staples of The Nice (before ELP).
