When, as a young man, Ali Akbar Khan received the title “ustad” (master musician), his father reportedly laughed. A half-century later, no one could doubt the designation: Khan, who plays the 25-string sarode, may be the most influential classical Indian musician alive. Based in California for more than 30 years, Khan has both taught and performed extensively, transforming Western understanding of Indian music—and winning a MacArthur “genius grant” and an NEA National Heritage Fellowship (to be awarded next month). Part of the official celebration of 50 years of Indian independence but open to the public, this concert will demonstrate the intricate counterpart that has earned Khan another appellation: “the Indian Johann Sebastian Bach.” At 7:30 p.m. at the Kennedy Center’s Eisenhower Theater. $12.50-40 (proceeds benefit the India Cultural Center).
