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.

With the addition of Stirratt, Coomer, and Johnston just prior to the recording of Anodyne, Farrar and Tweedy's relationship became more tumultuous, leading to verbal altercations after concerts. In one account, Tweedy recalled:  Around this time, I would say something into a microphone onstage, and afterward [Farrar would] pull me aside and say, "Don't you ever fucking talk into that microphone again." He would misconstrue me talking into the microphone as more evidence of my out-of-control, rampant ego, more evidence of me feeling like I didn't have to be so fucking afraid anymore.  Tweedy felt the new members gave him a new opportunity to contribute to the band, but Farrar felt disdain for Tweedy's new carefree attitude. Years later, Farrar would claim that he had been tempted to quit the band after seeing Tweedy stroking the hair of Farrar's girlfriend, an act which he believed to have been a proposition. In January 1994, Farrar called manager Tony Margherita to inform him of his decision to leave the band. Farrar told Margherita that he was no longer having fun, and didn't want to work with Tweedy anymore. Soon after the breakup, Farrar explained his departure: "It just seemed like it reached a point where Jeff and I really weren't compatible. It had ceased to be a symbiotic songwriting relationship, probably after the first record."  Tweedy was enraged that he heard the news secondhand from Margherita, since Farrar decided not to tell him in person. The following day, the two singers engaged in a verbal confrontation. As a favor to Margherita--who had spent a substantial amount of money to keep the band running--Farrar agreed to a final tour with Uncle Tupelo in North America. Tweedy and Farrar again engaged in a shouting match two weeks into the tour, due to Farrar's refusal to sing harmony on any of Tweedy's songs. The band made its first appearance on national television during the tour when they were featured on Late Night with Conan O'Brien. Sire had requested that the band perform "The Long Cut" on the show, which further irked Farrar since the song was written and sung by Tweedy. Uncle Tupelo's last concert was May 1, 1994, at Mississippi Nights in St. Louis, Missouri. Tweedy and Farrar each performed nine songs during the concert, and Mike Heidorn performed as drummer during the encore.  Following Uncle Tupelo's final tour, Tweedy encouraged his bandmates to join him in a new group, while Farrar searched for members for a band of his own. Tweedy was able to retain the rest of the Uncle Tupelo lineup, and created Wilco. Wilco began rehearsing a few days after the final Uncle Tupelo concert, and by August 1994 they were in the recording studio for their first album, A.M.. Farrar asked Jim Boquist to join his new band, Son Volt; Boquist was a multi-instrumentalist who had performed with Joe Henry as the opening act on Uncle Tupelo's last tour. Boquist also recruited his brother Dave, and Farrar convinced Mike Heidorn to leave Belleville to join the group. Farrar's new four-piece began recording their debut album Trace in November 1994.  Wilco signed to Reprise Records while Son Volt signed with Warner Bros. Records. Son Volt had an early college rock hit with "Drown" from the album Trace, but Wilco maintained a more commercially successful career in the years to follow. Regarding the possibility of a reunion, Mike Heidorn reported in a PopMatters interview that "nothing's ever for sure, but I would have to say, 'No such thing' ". Farrar said that he does not want the band to get back together, while Tweedy said that he believes that a reunion would not be productive musically.  Farrar and Tweedy sued Rockville Records and Dutch East India Trading CEO Barry Tenenbaum in 2000 over royalties that the label allegedly owed them, winning reparations from Tenenbaum and the joint rights to Uncle Tupelo's first three albums. After securing the rights, the band released a compilation entitled 89/93: An Anthology. In 2003, Uncle Tupelo re-issued their first three albums, which before the lawsuit had cumulatively sold over 200,000 copies.  As The Primitives, Tweedy and Farrar were highly influenced by punk bands such as The Ramones and The Sex Pistols. However, they began to listen to country music because punk rock was not well received in the Belleville and St. Louis music scenes. While they originally were introduced to country by their parents, it wasn't until this time that they began to listen to it for leisure. Farrar typically wrote songs about Middle America, while Tweedy wrote about more mainstream topics such as relationships. Farrar took influence from authors such as Kurt Vonnegut and Jack Kerouac, whom he read while working at his mother's bookstore. As the lead singer of Uncle Tupelo, Farrar's lyrics would be front-and-center during performances, but the band's musical style was mostly driven by Tweedy and Heidorn (seen in the music's Minutemen-influenced start-stop arrangement). Jeff Tweedy said in an interview with the St. Louis Post-Dispatch:  We probably have more influences than we know what to do with. We have two main styles that have been influences. For instance, we like Black Flag as much as early Bob Dylan and Dinosaur Jr. as much as Hank Williams ... To us, hard-core punk is also folk music. We draw a close parallel between the two. We'll play both in the same set if we get a chance. We don't have any biases as far as music is concerned.  Tweedy in particular was inspired by the Minutemen, and wrote a song about D. Boon following Boon's death in a van accident. The band has released songs originally performed by Creedence Clearwater Revival, The Carter Family, Lead Belly, Gram Parsons, The Soft Boys, The Louvin Brothers, Texas Tornados, and The Stooges. Releasing March 16-20, 1992 when alternative music was breaking through was a move inspired by Neil Young's decision to release the challenging albums On the Beach and Tonight's the Night immediately after the commercially successful Harvest. Critic Michael Corcoran likened the band's musical style to "Bob Mould fronting Soul Asylum on a speeded-up version of a Gram Parsons song."
