The show that night was billed as the Thelonious Monk Trio. Monk, 35, was already a prolific composer and piano innovator, yet it would take a decade for his brilliance to be fully appreciated by mainstream America. The trio was rounded out by Charles Mingus, 31, on standup bass and the youngster Roy Haynes, a 28-year-old hotshot drummer everyone called “Snap Crackle.” – The New York Times
