Things I didn’t know about him [from the NYT Obit]:
In 1960, at 30, he was finally persuaded by the saxophonist Cannonball Adderley to join the tide of Detroit musicians who had moved to New York. He continued living in the metropolitan area for the rest of his life, teaching and performing almost nonstop and appearing on albums like the trumpeter Lee Morgan’s 1964 hit “The Sidewinder.”
Not long after arriving, he became friends with Pannonica de Koenigswarter, the heiress and musicians’ advocate known as the jazz baroness, and she invited him to take up residence at her sprawling home in Weehawken, N.J., overlooking Manhattan and teeming with scores of cats. (Ms. de Koenigswarter arranged for Mr. Harris to stay in the house after she died; he continued living there for the rest of his life.)
In 1972, Thelonious Monk moved in, and he stayed until his death 10 years later. So Mr. Harris carried on at the elbow of a fellow master, trading information and further soaking up his language. The Monk songbook remained a pillar of Mr. Harris’s repertoire throughout his life; perhaps thanks in part to his time spent living with Monk, his playing grew both more lyrical and more tautly rhythmic as he got older.
