Prior to joining The Voice, Vachal released two EPs. Her first EP, Appleseed, was released in 2011, and her second, Crinkle Bloom, in 2014. Vachal auditioned for the ninth season of The Voice, singing "Dream a Little Dream of Me". With the exception of Adam Levine whose team was full, all coaches, Gwen Stefani, Pharrell WIlliams and Blake Shelton, turned their chairs for her and she eventually chose Williams as her coach. Vachal advanced to the Knockout rounds, but lost to Madi Davis. Levine and Shelton then opted to steal her, with Vachal choosing Levine as her new coach. Vachal's performances charted consistently, and her version of Drake's Hotline Bling charted at No. 28 on Billboard's Digital Songs chart.A week later, her rendition of Taylor Swift's Blank Space charted at No. 24. She was eliminated in the semifinals, but Vachal stated that she'll be working on her first full-length album soon.
