Keith Emerson was the British rocker who in the early 1970s helped define live performances on electronic musical instruments such as the modular Moog. He gained fame as a musical composer and clever keyboardist for The Nice before forming Emerson, Lake & Palmer and recording a string of hits for the influential supergroup. With high profile tours and live performances all around the world, Keith helped set the standard in high-tech gear. With towers of keyboards and large patch chord towers, the stage often looked like a spaceship, with sounds to match. His early work in synthesizers helped establish friendships with many of the innovators at the time including Dr. Robert Moog.
