The fiddle might be country music’s most dynamic instrument, and in Jenee Fleenor’s hands, it consistently becomes the star of the song. While Fleenor’s session work also includes mandolin and acoustic guitar, her fiddle—by turns as poignant as pedal steel, as electrifying as a chicken-pickin’ guitar solo—lends emotional resonance to every song it touches, making her a favorite of big-time artists like Blake Shelton and Sam Hunt.
