Henry Threadgill, NEA Jazz Master and one of the world's leading avant-garde composers and arrangers, turns 82 on February 15. To celebrate, we present a 2014 Harlem Stage concert honoring his 70th birthday, curated by pianist Jason Moran. Dozens of musicians who have played alongside Threadgill throughout his storied career gathered to perform his groundbreaking compositions while the maestro himself watched from the audience.
