The correct answer is Tommy Flanagan!
Known for his flawless and tasteful playing, Tommy Flanagan received long overdue recognition for his talents in the 1980s. He played clarinet when he was six and switched to piano five years later. Flanagan was an important part of the fertile Detroit jazz scene (other than 1951-1953 when he was in the Army) until he moved to New York in 1956. He was used for many recordings after his arrival during that era; cut sessions as a leader for New Jazz, Prestige, Savoy, and Moodsville; and worked regularly with Oscar Pettiford, J.J. Johnson (1956-1958), Harry “Sweets” Edison (1959-1960), and Coleman Hawkins (1961). Flanagan was Ella Fitzgerald’s regular accompanist during 1963-1965 and 1968-1978, which resulted in him being underrated as a soloist. However, starting in 1975, he began leading a series of superior record sessions and since leaving Fitzgerald, Flanagan has been in demand as the head of his own trio, consistently admired for his swinging and creative bop-based style. Among the many labels he has recorded for since 1975 are Pablo, Enja, Denon, Galaxy, Progressive, Uptown, Timeless, and several European and Japanese companies. For Blue Note, he cut Sunset and Mockingbird in 1998, followed a year later by Samba for Felix. Despite a heart condition, Flanagan continued performing until the end of his life, performing two-week stints at the Village Vanguard twice a year, recording and touring. He died on November 16, 2001, in Manhattan from an arterial aneurysm.
