The subway opera singer with the voice of an angel has made her public debut post-going viral. Emily Zamourka was homeless when she was captured singing in the subway by a Los Angeles police officer. The video drew massive attention online, changing the course of Zamourka's life. She said she became homeless after a thief smashed her $10,000 violin. Before that, she was a popular street performer in downtown L.A. Zamourka has since played her first professional gig since the video emerged.
