Released three years after their breakout sophomore album Something to Write Home About, On a Wire was a massive departure from the band's established sound, eschewing the brighter pop-punk that helped define emo as a genre in favor of a darker, more adult sound inspired by 70's rock bands like Led Zeppelin.

Reception to the album was extremely divisive, and is widely seen as having derailed the band's career just as emo was starting to break into the mainstream with contemporaries like Jimmy Eat World and Dashboard Confessional receiving extensive radio play.

After touring extensively to support Something to Write Home About, the band was looking to depart from their high-energy powerpop style in lieu of a slower, more mellow sound.

Unlike the band's previous work, which they played extensively at live shows before recording, On a Wire was written entirely in the studio, leading to a much less energetic sound.

[4] Years later, Jim Suptic remarked that had the band toured the songs before recording, the resulting album would have been "less acoustic and heavier in parts.

[8][9] The rest of the album was recorded in January and February 2002 at Tarquin Studios in Bridgeport, Connecticut with Litt[7] over the course of six weeks.

Ed Rose, who had worked with the band previously, provided additional creative input on "Overdue" while Carl Nappa did digital editing.

[12] Musically, the album's sound has been classed as alternative country,[13][14] americana[10] and indie rock,[15] drawing comparisons to the Promise Ring's Wood/Water (2002),[16][17] Wilco and the Dream Syndicate.

[10] It marked a shift away from the group's earlier pop punk/emo sound[16][18] and replaced it mainly with acoustic guitars, quiet vocals[18] and more prominent keyboards.

[17][19] Andrew Sacher of BrooklynVegan wrote that this departure did not seem as drastic for Pryor, who had been exploring similar sounds with his side effort the New Amsterdams.

"[12] On March 22, 2002, On a Wire was announced for release in two months' time; alongside this, the album's track listing and artwork were posted online.

[25] In May and June, the group went on a headlining US tour[24] with support from Hot Rod Circuit, the Jealous Sound, Rhett Miller and Audio Learning Center.

[11] The band spent a week at home, before going on an east coast US tour[27] in June and July with Superchunk and Hot Rod Circuit.

[26] After this, they performed "Stay Gone" on the Late Night with Conan O'Brien, and appeared at the Fuji Rock Festival in Japan.

[32][33] A music video for "Stay Gone", directed by Brock Batten and Jonathan Green, was released on the Vagrant Records Another Year on the Street Vol.

In an interview with AP Magazine, lead singer Matt Pryor considered that the dramatic change in style for On a Wire seriously impacted the momentum the band had gained from Something to Write Home About, allowing later bands such as Dashboard Confessional to take much of the fan base that the Get Up Kids had previously earned.

Speaking in 2019, Pryor said "I’ve been making the joke for a while that On A Wire is our Paul's Boutique where it’s like … [it] didn’t do well when it came out, but now, [fans say] 'Oh, it’s my favorite record!'
