The album was re-released in the UK in 2004 with two extra tracks, before being exported to the U.S. (without the bonus tracks). The album was also released on SACD and DualDisc with 5.1 Surround mixes.
The band's A&R representative Jim Chancellor explained the reasons for choosing rock producer Jacknife Lee to oversee the record by saying, "I wanted a record for them that was bigger and bolder and a lot different than their previous records. I wanted them to make a more of a rock album than an indie record." Chancellor, Lee and the band chose fifteen songs to start working on out of an original pool of 24. Critical to the new direction was Lightbody's development into a more rounded songwriter. "They played us some songs which were not indie. There were a couple of pop songs and then 'Run', which is an enormous emotional rollercoaster of a track," said Chancellor.
During the first couple of weeks in the studio the band found it quite difficult to adapt from an 'indie'-orientated sound to a more commercially viable pop rock sound. Producer Lee offered constructive suggestions about how to both simplify their songs and augment them with other sounds such as strings, and Snow Patrol proved very receptive to his advice. According to Chancellor, "Some bands tend to be more defensive about what goes on in the studio. Snow Patrol weren't. They were very much like, 'Yeah, we really want to be successful this time.'"
The lyrics, all written by Lightbody are about failing relationships and break-ups. They were inspired by his personal experiences. Quinn, his longtime friend, says that he knows who Lightbody sings about in those songs. The lyrics deal with the themes of relationships and politics. Lightbody has said that his "finally learn[ing] to write a chorus" was the key to the album's success.
Guitarist Nathan Connolly joined the band during the recording sessions. He did not contribute much, as the whole album had already been demoed. He commented that he found it easy to start writing and sharing his ideas with the rest of the band, as he had a good relationship with the band before being a member. The album's music incorporates distorted guitar, feedback styles, and the vocals are gritty. The band's sound on the album was described as being a "cross between the sullen folk of Nick Drake and the more punchy rock moments of Simple Minds and the Pixies. Reviewing the album, Pitchfork described the performances as being based around "rigid, unwavering tempos that approximate dance music," created through looped sections of playing augmented with electronics. The first song, "How to Be Dead", introduces this sound with extensive use of drum machine programming.
