The Modern Jazz Quartet (MJQ) was a jazz combo established in 1952 that played music influenced by classical, cool jazz, blues and bebop. For most of its history the Quartet consisted of John Lewis (piano), Milt Jackson (vibraphone), Percy Heath (double bass), and Connie Kay (drums). The group grew out of the rhythm section of Dizzy Gillespie's big band from 1946 to 1948, which consisted of Lewis and Jackson along with bassist Ray Brown and drummer Kenny Clarke. They recorded as the Milt Jackson Quartet in 1951 and Brown left the group, being replaced on bass by Heath. During the early-to-mid-1950s they became the Modern Jazz Quartet, Lewis became the group's musical director, and they made several recordings with Prestige Records, including the original versions of their two best-known compositions, Lewis's "Django" and Jackson's "Bags' Groove". Clarke left the group in 1955 and was replaced as drummer by Connie Kay, and in 1956 they moved to Atlantic Records and made their first tour to Europe.
Under Lewis's direction, they carved their own niche by specializing in elegant, restrained music that used sophisticated counterpoint inspired by baroque music, yet nonetheless retained a strong blues feel. Noted for their elegant presentation, they were one of the first small jazz combos to perform in concert halls rather than nightclubs. They were initially active into the 1970s until Jackson quit in 1974 due to frustration with their finances and touring schedule, but re-formed in 1981. They made their last released recordings in 1992 and 1993, by which time Kay had been having health issues and Mickey Roker had been his replacement drummer while Kay was unavailable. After Kay's death in 1994, the group operated on a semi-active basis, with Percy Heath's brother Albert Heath on drums until the group disbanded permanently in 1997.
History
Background, formation, departure of Kenny Clarke, and Prestige recordings (1946–1955) Two of the four founding members of the Modern Jazz Quartet, pianist John Lewis and drummer Kenny Clarke, met and first performed together in 1944 while stationed with the US army in France during World War II. In 1946, they reconnected in New York, where Clarke, who had joined his friend Dizzy Gillespie's big band, introduced Gillespie to Lewis, who went on to replace Thelonious Monk as the band's pianist. The band's rhythm section now consisted of Lewis (piano), Milt Jackson (vibraphone), Ray Brown (bass), and Clarke (drums). On Gillespie's encouragement, they began to perform improvised renditions of jazz standards as a standalone unit between sets of the big band's music, as an entr'acte, a practice that had been accepted in jazz since Benny Goodman introduced his trio in 1935. Jackson later recalled: "From the first time we performed in that band as a quartet, we became prominent and a part of the band. We would play fifteen to twenty minutes, two or three tunes, and everybody loved it, including Dizzy and the band." Upon the dissolution of Gillespie's band, the rhythm section considered continuing as a quartet under Jackson's name, but they went in their own directions for the next three years. On August 18, 1951, they made a recording as the Milt Jackson Quartet for Gillespie's record label, Dee Gee Records. Brown then left the group to concentrate on working with his wife, singer Ella Fitzgerald, and was replaced as bassist by Percy Heath, who had also performed with Gillespie. The quartet was incorporated on January 14, 1952, as the Modern Jazz Society, Inc., of which the Modern Jazz Quartet became the working entity. Three or four names were considered, including the New Jazz Quartet, before the group decided to use the name Modern Jazz Quartet. In a 1992 interview, Lewis said of the name: "It was an arbitrary name, the quickest name we could get cleared for a corporation in New York state. It had nothing to do with a description of the music." Heath later recalled a conversation between the group members that occurred in Jackson's Cadillac on the way home from a nightclub date that led up to the creation of the Modern Jazz Quartet:
