Armando Anthony "Chick" Corea (born June 12, 1941) is an American jazz pianist, keyboardist, and composer. Many of his compositions are considered jazz standards. As a member of Miles Davis' band in the 1960s, he participated in the birth of the electric jazz fusion movement. In the 1970s he formed Return to Forever. Along with Herbie Hancock, McCoy Tyner and Keith Jarrett, he has been described as one of the major jazz piano voices to emerge in the post-John Coltrane era. His career has been driven by his will to operate as a free agent and compulsively explore different avenues of music making. This hunger has positioned him as an important catalyst in the world of serious, mainstream acoustic jazz, and he is one of the most influential and widely studied figures in the last 40 years. Corea continued to pursue other collaborations and to explore various musical styles throughout the 1980s and 1990s. He is also known for promoting and fundraising for a number of social issues, such as eradicating social illiteracy, and is a Scientologist.
