Wynton Marsalis official web site

Wynton Marsalis played the trumpet on Monday night at the Apollo Theater after a monthlong hiatus caused by a lip inflammation. The occasion was Jazz at Lincoln Center’s fifth annual spring gala, which featured guest performances by Joe Cocker, Tracy Chapman, John Mayer, John Legend and Natalie Merchant.
Throughout the evening Wynton was onstage with his septet, which served as a house band.
He joined his bandmates on a succession of background horn arrangements, including one for “Unchain My Heart” that featured Mr. Cocker. He also ventured a few brief solos, sounding less tentative as the night progressed. His most obvious exertion was on “All Blues,” a Miles Davis song that Mr. Mayer had chosen to perform.
Last month Wynton’s lips injury caused the postponement of a concert with the Orion String Quartet that was to have closed Jazz at Lincoln Center’s season.
It has been rescheduled for September 20, 2006.

Due to a recurring inflammation of his lip, Wynton has been advised by his doctor to take several weeks off from playing the trumpet and so regretfully will have to cancel some of his scheduled engagements. It is Wynton’s hope that by resting now, he will avoid having this problem come up again.

Due to cellulitis of the lip (inflammation of connective tissue), Wynton’s doctor instructed him not to perform for 30 days.
So Wynton’s manager cancelled the August activities so that he can finally take the time needed to heal properly.
