She's back! The Grammy award-winning singer Billie Eilish is hitting the road. Eilish first turned musical ears when the song she wrote with her talented brother went viral in 2015. "Ocean Eyes" was just a taste of things to come and heralded a bold, out-of-the-box pop persona that mixes avant-garde fashion and a tough-as-nails swagger, all tied up with an incredibly expressive voice.
