Keith Emerson (November 2, 1944 - ) British keyboard player and composer. Formerly a member of The Nice, a group who produced genuinely inspired music, he went on to start Emerson Lake and Palmer, one of the first supergroups, whose music often included musical bits by Bach, Janacek, Bartok, Ginastera, Copland, Mussorgsky and other classical composers. He has also composed film soundtrack music.
He is known for his technical virtuosity and for his live antics, including using knives to hold down keys during solos. Along with contemporaries Jon Lord of Deep Purple and Rick Wakeman of Yes, Emerson is widely regarded as one of the top keyboard players of the progressive rock era.
