Lawrence Elliott Willis was an American jazz pianist and composer. He performed in a wide range of styles, including jazz fusion, Afro-Cuban jazz, bebop, and avant-garde.
Willis was born in New York City. After his first year studying music theory at the Manhattan School of Music he began performing regularly with Jackie McLean. After he graduated he made his first jazz recording, McLean's Right Now! in January 1965, which featured two of Willis' compositions. His first recording of any type, however, was as a singer with the Music and Arts Chorale Ensemble, performing an opera by Aaron Copland under the direction of Leonard Bernstein. He decided to concentrate on jazz because of the difficulties African-American musicians had in finding work in concert music.
Throughout his career he performed with a wide range of musicians, including several years as keyboardist for Blood, Sweat & Tears. He spent several years as pianist for trumpeters Nat Adderley and Woody Shaw as well as long and productive tenures with Roy Hargrove and with Jerry Gonzalez and his Fort Apache Band. His late recording with Paul Murphy, Exposé, demonstrated the fusion principles of bebop and avant-garde jazz.
