Jay Stuart Farrar is an American songwriter and musician currently based in St. Louis. A member of two critically acclaimed music groups, Uncle Tupelo and Son Volt, he began his solo music career in 2001. Beyond his established talents as a songwriter, he is a guitarist, pianist, harmonicist, and a vocalist.

Uncle Tupelo was an alternative country music group from Belleville, Illinois, active between 1987 and 1994. Jay Farrar, Jeff Tweedy, and Mike Heidorn formed the band after the lead singer of their previous band, The Primitives, left to attend college. The trio recorded three albums for Rockville Records, before signing with Sire Records and expanding to a five-piece. Shortly after the release of the band's major label debut album Anodyne, Farrar announced his decision to leave the band due to a soured relationship with his co-songwriter Tweedy. Uncle Tupelo split on May 1, 1994, after completing a farewell tour. Following the breakup, Farrar formed Son Volt with Heidorn, while the remaining members continued as Wilco.
