Gianandrea Noseda is the music director of the National Symphony Orchestra. He is also one of the best interviewees in all of music (as Jay knows from experience). Noseda was in New York, to guest-conduct the Metropolitan Opera Orchestra, and Jay sat down with him — to talk about orchestras, Mozart, Mahler, YouTube, and more. At the end, Jay says, “Can you possibly put into words why you like music?” A conversation with Noseda is equal parts deep and fun.
