Big Paul is an original composition by pianist Tommy Flanagan, written for and named after bassist Paul Chambers. The tune was first recorded on May 19, 1957, at Rudy Van Gelder's studio in Hackensack, New Jersey, during a session led by the Paul Chambers Quintet that also featured Donald Byrd on trumpet, Clifford Jordan on tenor saxophone, and Elvin Jones on drums. The recording was not released immediately; it first appeared in 1962 as part of the album issued under the title Kenny Burrell and John Coltrane on the New Jazz label, and was later reissued on Prestige. Flanagan composed the piece during his prolific early period as one of the most in-demand sidemen on the New York hard bop scene, a time when he was also recording with Miles Davis, Sonny Rollins, and John Coltrane. His writing on Big Paul reflects the melodic restraint and bebop classicism that defined his style, drawing on influences from Art Tatum, Charlie Parker, and fellow Detroit pianists Hank Jones and Barry Harris. The tune remains a deep cut in Flanagan's catalog, with no known cover versions or reinterpretations by other artists, making it a rare window into his less celebrated but characteristically elegant work as a composer rather than an accompanist.
