The Keith Emerson Band played in front of more than 200,000 people.
Here's the festival's finale, as shared by Tony Ortiz, the ELP
biographer, on MySpace: Led Zeppelin's "Whole Lotta Love". Emerson
does harmonica or "didjeridoo"-like vocals on the mike. There's Eddie
Jobson on violin. I think I spot Belew as well. The Power Trio was
definitely in that festival. I think even Trey Gunn and Pat Mastelotto
were there. I believe there are also Tuva throat singers (a Mongolian
tribe, so not ffrom an island in the Pacific Ocean). Who else do you
spot in there?
