On Going: Lincoln Center White Light Festival: till November 22
Estonian composer Arvo Pärt likened his music to white light that contained all colors, and saw “the spirit of the listener” as the prism where those colors could appear. Lincoln Center’s White Light Festival, now in its sixth year, is dedicated to exploring that intersection between art and spirit across a number of disciplines. Expect performances from Mark Padmore and Paul Lewis, Dialogos and Kantaduri, and New York City’s very own jazz legend Wynton Marsalis.
