Carl Palmer

Drummer is recuperating ahead of summer ELP tribute tour.

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

Fans searching for an answer as to why Emerson, Lake and Palmer are unlikely to ever play again need only listen to their final reunion performance, drummer Carl Palmer says. For him, their set at 2010's High Voltage Festival was simply not up to the group's lofty standards -- despite a lengthy acclimation period beforehand.
