John Adams (Nixon In China, Doctor Atomic) is a Pulitzer and Grammy-winning composer who’s one of the biggest living names in the world of opera and classical music. He’s helped give opera a more contemporary lens by steering his work toward big political events in modern history. His latest opera, “Girls of the Golden West,” looks at the California Gold Rush, and it was recently nominated for two Grammys. John joins Tom Power to discuss his decades-long career in music, his Pulitzer Prize-winning composition inspired by 9/11, and what role he thinks classical music can play when it comes to telling contemporary stories.
