Nineteen-year-old Harmony McKee impressed coaches Riley Green and Adam Levine during The Voice's Blind Auditions with her performance of Miranda Lambert's "Gunpowder & Lead," despite it being her first-ever country song performance. Her strong vocal ability led both coaches to turn their chairs, though she typically works in R&B, rock, and blues rather than country music.

McKee revealed she had sung some Johnny Cash with her grandmother, creating a connection with Green, who similarly began his musical journey with his grandfather. After hearing pitches from both coaches, McKee selected Riley Green as her mentor, though the studio audience's notably quiet reaction to this choice surprised Green himself, who subsequently remarked on the satisfaction of beating Adam Levine.
