Through interactive performances and lessons, young audiences at Jazz at Lincoln Center’s Jazz for Young People will go on Duke’s journey from Washington, DC, to New York City, where he digs deep into this music called jazz as it is being birthed from the belly of New Orleans. The Jazz at Lincoln Center Orchestra with Wynton Marsalis will illustrate how Ellington’s discovery of the blues and development of his own innovative ideas created a new vernacular that would forever change the musical landscape of jazz. His legacy as a composer, a leader, and a vanguard of American music is celebrated in this hour-long, youth-oriented event. Peter Jay Sharp Theatre, Symphony Space, 2537 Broadway at W. 95th St. Nov. 21, 11 a.m. & 1 p.m. Tickets are $10-$25 at symphonyspace.org.
