Gregory Stuart Lake (10 November 1947 – 7 December 2016) was an English bassist, guitarist, singer, songwriter, and producer who gained prominence as a founder member of the progressive rock bands King Crimson and Emerson, Lake & Palmer (ELP).
Born and raised in Dorset, Lake began to play the guitar at the age of 12 and wrote his first song, "Lucky Man", at the same age. He became a full-time musician at 17, playing in several rock bands until fellow Dorset guitarist Robert Fripp invited him to join King Crimson as their singer and bassist. They found commercial success with their influential debut album, In the Court of the Crimson King (1969). Lake left the band in 1970 and achieved significant success in the 1970s and beyond as the singer, guitarist, bassist, and producer of ELP. As a member of ELP, Lake wrote and recorded several popular songs including "Lucky Man" and "From the Beginning". Both songs entered the UK and US singles charts.
Lake launched a solo career, beginning with his 1975 single "I Believe in Father Christmas" which reached number two in the UK. He went on to release solo albums and singles thereafter, collaborating with several artists in the process. Lake performed with various groups in the 1980s, and occasional ELP reunions in the 1990s, and toured regularly as a solo artist into the 21st century. He died on 7 December 2016 in London, after suffering from cancer, at the age of 69.
