Soprano Renée Fleming  has a new album titled Dark Hope, on which she covers indie rock acts like Muse, Arcade Fire, Duffy and the Mars Volta.

In a way, it’s in keeping with “the people’s diva” who sang at President Obama’s inauguration and has previously ventured into jazz. But vocally, it’s a radical departure from her previous work. She talks about the new Fleming voice, rock music, and her career at 51.
