The Barbarian - Live At The Lyceum Theatre, London, UK, 09/12/70

ELP keyboardist Keith Emerson was not against borrowing from classical music. This instrumental is a pretty direct takeoff from "Allegro Barbaro," a piano piece by Bela Bartok. A group arrangement, it shows off some of the musicianship the group would become known for, including Emerson's high-speed piano and Carl Palmer's deft drumming.

This was the first track on the first Emerson, Lake & Palmer album. A very intense track, it was offset by the more mellow "Take A Pebble," which came next.
