His first session as a leader was cut for Blue Note in November 1956, and over the next few months he recorded for Savoy and Specialty as well, often working closely with Hank Mobley or Benny Golson. Later in 1957, he performed as a sideman on John Coltrane's classic Blue Train, as well as with Morgan's early sessions showed him to be a gifted technician who had his influences down pat, but subsequent dates found him coming into his own as a distinctive original stylist. That was most apparent on the Blue Note classic Candy, a warm standards album completed in 1958 and released to great acclaim. Still only 19, Morgan's playing was still imbued with youthful enthusiasm, but he was also synthesizing his influences into an original sound of his own. Also in 1958, Gillespie's big band broke up, and Morgan soon joined the third version of Art Blakey's Jazz Messengers, which debuted on the classic Moanin' album later that year. As a leader, Morgan recorded a pair of albums for Vee Jay in 1960, Here's Lee Morgan and Expoobident, and cut another for Blue Note that year, Leeway, with backing by many of the Jazz Messengers. None managed to measure up to Candy, and Morgan, grappling with heroin addiction, wound up leaving the Jazz Messengers in 1961. He returned to his hometown of Philadelphia to kick the habit, and spent most of the next two years away from music, working occasionally with saxophonist Jimmy Heath on a local basis.
