Drummer extraordinaire Carl Palmer leads a tour celebrating the legacy of progressive-rock supergroup Emerson, Lake & Palmer. The trio were known for their classical influences, instrumental virtuosity and a string of platinum albums in the 1970s that made songs such as “Lucky Man,” “From the Beginning” and “Karn Evil 9” staples of rock radio. With full cooperation from the estates of his late bandmates, Keith Emerson and Greg Lake, Palmer developed this production, which combines live performance by Palmer and his current band with video of Emerson and Lake from a 1992 ELP concert.
