A.M. is the debut studio album by the American alternative rock band Wilco, released on March 28, 1995, by Sire Records and Reprise Records. The album was released only months after the breakup of Uncle Tupelo, an alternative country band that was the predecessor of Wilco. Prior to its release, there was debate about whether the album would be better than the debut album of Son Volt, the new band of former Uncle Tupelo lead singer Jay Farrar. Although A.M. was released before Son Volt's Trace, critical reviews were modest and initial sales were low. The album was later regarded as a "failure" by band members, as Trace was a greater success. It was the band's last album to be recorded in a purely alternative country style, as following the record the band began to expand their sound across multiple genres. It is also the only Wilco album to feature Brian Henneman of The Bottle Rockets as a lead guitarist. Background and recording Uncle Tupelo's final album, Anodyne, featured a new lineup for the band—a five-piece outfit with drummer Ken Coomer, bassist John Stirratt, and multi-instrumentalist Max Johnston. Tensions mounted between singers Jay Farrar and Jeff Tweedy, and Uncle Tupelo played its last concert on May 1, 1994, at Mississippi Nights in St. Louis, Missouri. Only days after the breakup, Tweedy decided to form a new group. He was able to retain the lineup of Uncle Tupelo sans Farrar, and rechristened the band Wilco. In mid-May, the band began to rehearse songs in the office of band manager Tony Margherita, and hired producer Brian Paulson, who produced Anodyne. Wilco first recorded demo tracks for the album at Easley studio in Memphis, Tennessee, in June. Stirratt recommended the studio based on previous experience as a member of The Hilltops, and Tweedy had heard of the studio through a Jon Spencer Blues Explosion recording. Reprise Records, a subsidiary of Warner Bros,, signed Jeff Tweedy after hearing the tapes, and recording for the album continued through August. Tweedy was preoccupied with trying to establish Wilco as a viable band on the Reprise label, and decided to add another guitarist to the band. Brian Henneman, the lead singer for The Bottle Rockets, was brought into the recording sessions as a lead guitarist. Steel guitarist Lloyd Maines and bassist Daniel Corrigan also contributed to the album. Corrigan also photographed the band for the liner booklet.
