The jazz saxophonist whose music was once a hit with the “don’t trust anyone over 30” crowd turns 75 this year. Charles Lloyd doesn’t play much jazz for hippies anymore, although his compositions are still often flavored with Eastern concepts; instead, he works in delicate, often exquisite renderings of the music—usually with his virtuosic and sensitive quartet (pianist and Kennedy Center jazz advisor Jason Moran, bassist Reuben Rodgers, and drummer Eric Harland). Still, Lloyd hasn’t completely abandoned that era’s yearning for freedom. His birthday celebration promises to include a variety of dimensions: His quartet will be there, but Lloyd will also work with musicians like Indian tablaist Zakir Hussain, lyra player Sokratis Sinopoulos, and Greek vocalist Maria Farantouri. He’ll also duet with Moran, with whom he took some freeform excursions on their recent CD Hagar’s Song. By the end of the evening, the flower children won’t be the only ones with expanded minds.

Charles Lloyd performs at 8 p.m. at the Kennedy Center Concert Hall, 2700 F St. NW. $20-$65. (202) 467-4600. kennedy-center.org.
