Since 1988, Wynton Marsalis has led the 15-piece Jazz at Lincoln Center Orchestra, which simultaneously honors the rich heritage of Duke Ellington and Louis Armstrong while presenting a stunning variety of new works from illustrious names, many of whom perform regularly with the ensemble. From swinging to supple, it’s all sheer jazz perfection — and no wonder these annual appearances have become a favorite of UMS audiences. “You know it’s a good gig when you can’t tell if the band or the audience is having more fun.” (Milwaukee Journal-Sentinel)
