Jeffrey Scot Tweedy (born August 25, 1967 in Belleville, Illinois, United States) is an American songwriter, musician and leader of the band Wilco. Tweedy joined rockabilly band The Plebes with high school friend Jay Farrar in the early 1980s, but Tweedy's musical interests caused one of Farrar's brothers to quit. The Plebes changed their name to The Primitives in 1984, and subsequently to Uncle Tupelo. Uncle Tupelo garnered enough support to earn a record deal and to tour nationally. After releasing four albums, conflicts between Tweedy and Farrar caused the band to break up in 1994.
