Emerson Lake & Palmer

Drummer will play alongside footage of late bandmates Keith Emerson and Greg Lake.

This was both the boldest move the band ever made, and the beginning of their undoing.

Emerson, Lake & Palmer reunited for a 40th anniversary concert at the High Voltage Festival in 2010. Sadly for fans, they never performed together again.

Emerson, Lake & Palmer singer, bassist and guitarist Greg Lake died on Dec. 7 after what is described as "a long and stubborn battle with cancer."

Emerson Lake and Palmer bandmate Carl Palmer has confirmed that Keith Emerson passed last night in Santa Monica, Calif.
