Some of the world's greatest keyboardists -- including Keith Emerson, Jan Hammer, Jordan Rudess, Bernie Worrell, Roger O'Donnell and DJ Logic -- come together for these live performances filmed at the Moogfest music festival, held inside New York City's legendary B.B. King Blues Club in 2006. The annual festival honors the contributions of inventor Robert Moog (1934-2005) and the namesake analog synthesizers he created.
