Background: All Time Low is an American rock band from Towson, Maryland, a suburb of Baltimore, formed in 2003. The band currently consists of lead vocalist and rhythm guitarist Alex Gaskarth, lead guitarist and backing vocalist Jack Barakat, bassist and backing vocalist Zack Merrick and drummer Rian Dawson. The band's name is taken from lyrics in the song "Head on Collision" by New Found Glory. The band consistently tours year-long, has headlined numerous tours, and has appeared at music festivals including Warped Tour, Reading and Leeds and Soundwave.
Context: Formed while still in high school in 2003, All Time Low began covering songs by pop punk bands such as Blink-182. The band's line-up included Alex Gaskarth on vocals, Jack Barakat on guitar, TJ Ihle on lead guitar and backing vocals, Chris Cortilello on bass, and Rian Dawson on drums. Cortilello and Ihle left the band, resulting in the band laying dormant until Zack Merrick joined on bass and Gaskarth picked up guitar. They released a four-song EP in November before signing to Emerald Moon Records in 2004. They released their second EP, titled The Three Words to Remember in Dealing with the End EP later that same year. The band released their debut studio album, The Party Scene, in July 2005.  In December, it was announced that the band was no longer signed, but were attracting attention from a number of record labels. In late 2006, the band performed a showcase for John Janick the founder of record label Fueled by Ramen. They were not signed because Cute Is What We Aim For had recently been taken on by the label, which was not in a position to sign another band at the time. The band was brought to the attention of Hopeless Records by fellow touring band Amber Pacific; on March 28, 2006, it was announced that All Time Low had signed with Hopeless. The band said in an interview that they were starting to get serious about music while in their senior year of high school; following their graduation, the members focused on the group full-time, and released the Put Up or Shut Up EP in July. The EP entered the Independent Albums chart at No. 20 and the Top Heatseekers at No. 12.  All Time Low began a busy tour in support the EP in late 2006. After the tour, the band began writing material for their second studio album.
