Emerson, Lake and Palmer, known to all as ELP, were progressive rock's first supergroup. Keith Emerson (keyboards) came from The Nice, Greg Lake (guitar, bass & vocals) from King Crimson and Carl Palmer (drums) from Atomic Rooster. Formed in 1970, they were an instant success and went on to have a series of huge selling albums throughout the seventies before splitting up in the early eighties. Reunited in the early nineties they produced a new album, Black Moon, and began to tour again. In 1997 they embarked on a world tour, which included this superb performance at Montreux on July 7.
