I'm glad this disc is still being chatted about. I thought I would add my thoughts.
I have the original DVD-A. My first DVD-A purchase. It's one of my favorite surround discs.
I tried to buy the SACD also from Music-Wow but they went out of business and kept my money.
Greg and company did a fantastic job producing this for surround.
I know some folks don't like the adventurous and aggressive mix with all it's pans, sweeps and spins. I assure however it sounds exactly as it should, it's as if you were sitting in the sound booth in the venue during the tour.
They traveled with a quadraphonic sound system.
I saw them several times during the 73-74 tours, the first was Madison Square Garden in NYC around Christmas '73. They had two large JBL speaker stacks on each side of the side, two more equally large stacks in the back behind the audience for quad.
During "Karn Evil 9" the synthesizers would sweep and pan around the stadium and several times it would shoot up over your head to the nest of horns on the ceiling that is the Garden's P.A. system for basketball games ( 5.0 quintaphonic even ) . Greg's guitar solos, Carl's Moog drum solo, Keith's end-over-end piano solo all swirling around. A fantastic circus of sound, the largest surround system I ever heard.
They finished the show with a choir singing Silent Night while a snow machine covered the stage in a fresh layer of fake snow from above.
....See the Show!
I found this site about it. See the snow.

The only detraction about the DVD-A for me is the inclusion of "Lucky Man". It shouldn't be there, it should be on a proper surround release of the first ELP album. They should have included the single "Brain Salad Surgery" or "Tiger in the Spotlight" instead.
I'm still waiting for the first album and Tarkus, Trilogy, etc. C'mon Greg, hop to it.
I'll buy them all.
