Snow Patrol are a Northern Irish rock band formed in 1993, consisting of Gary Lightbody (vocals, guitar), Nathan Connolly (guitar, backing vocals), Paul Wilson (bass guitar, backing vocals), Jonny Quinn (drums), and Johnny McDaid (piano, guitar, backing vocals). Initially an indie rock band, the band rose to prominence in the early-mid 2000s as part of the post-Britpop movement. The band were founded at the University of Dundee in 1993 by Lightbody, Michael Morrison, and Mark McClelland as Shrug. After briefly using the name Polarbear and released the EP Starfighter Pilot (1997) and losing Morrison as a member, the band became Snow Patrol in 1997 and added Quinn to its line-up.

Snow Patrol said they would enter its "next phase" with their sixth album. The band took a new musical direction, and Connolly advised fans to keep an open mind regarding the new material. On 12 January 2011, Lightbody launched a blog to give details about the progress of the next release from the band.  Snow Patrol released the single "Called Out in the Dark" (remixed by Fatboy Slim) for radio airplay on Thursday 21 July 2011 on BBC Radio 1 on Zane Lowe's radio show. According to official sources, the single itself would be released independently and as part of an EP later on and the UK release date was said to be 4 September. More details on the EP were announced on 3 August, when the group's website revealed the artwork and track list contents. Along with the new single, the release contained three new tracks entitled "My Brothers", "I'm Ready", and "Fallen Empires". In addition, it was revealed that the EP was intended to be a digital release limited to the UK and Ireland.  Shortly after the premiere of the new lead single, the quintet's official website confirmed the news that the name of the new album would be Fallen Empires. Fallen Empires was released on 14 November 2011 in the UK and was launched at O2 Shepherd's Bush Empire. Singer-songwriter Johnny McDaid joined the band during the recording of the album.  The second single from Fallen Empires was "This Isn't Everything You Are", released on 13 November 2011.
