John Lenwood (Jackie) McLean was an alto saxophonist, composer, bandleader and educator, born in New York City.
His father, John Sr., who died in 1939, played guitar in Tiny Bradshaw's orchestra. After his father's death, his musical education was continued by his godfather, by his stepfather, who owned a record store, and by several noted teachers. He also received informal tutoring from neighbours Thelonious Monk, Bud Powell, and Charlie Parker. During high school he played in a band with Kenny Drew, Sonny Rollins, and Andy Kirk Jr. (the tenor saxophonist son of Andy Kirk).
He recorded with Miles Davis, on Davis' Dig album, when he was 19 years old. Rollins played on the same album. As a young man McLean also recorded with Gene Ammons, Charles Mingus, andGeorge Wallington, and as a member of Art Blakey's Jazz Messengers (he reportedly joined the Jazz Messengers after being punched by the notoriously violent Mingus and, fearing for his life, stabbing him in self-defence). His early recordings as leader were in the hard bop school. He later became an exponent of modal jazz without abandoning his foundation in hard bop. Throughout his career he was known for his distinctive tone (often described with such adjectives as withering, piercing, or searing), his slightly sharp pitch, and a strong foundation in blues.
