Partway through the process, vocalist Josh Franceschi suffered a panic attack, which resulted in him being hospitalized and the band losing time in the studio.

"No One Does It Better" was released as the third single from the album in April 2012, followed by "Reckless" as the fourth in October 2012, which preceded a one-off headlining show at Wembley Arena.

Sinners Never Sleep received generally positive reviews from music critics, some of whom complimented You Me at Six's songwriting and their change in style.

[2] In April 2010, vocalist Josh Franceschi and guitarists Max Helyer and Chris Miller spent time writing new songs together, while bassist Matt Barnes and drummer Dan Flint went to Las Vegas for a break.

While on the trek, Franceschi said their next album would be influenced by acts to whom they were listening, such as the Ghost Inside, A Loss for Words and Parkway Drive.

[4][5] In August 2010, Franceschi announced that You Me at Six would be writing for a new album as early as November, remarking that bands cannot tour for two years straight without new songs.

[5] They were aiming in a generalized rock direction, in the vein of Foo Fighters and Kings of Leon;[8] Franceschi admired that Jimmy Eat World did that between their Clarity (1999) and Chase This Light (2007) albums while retaining their identity.

Their label initially suggested a secluded forest location, a proposal that the extroverted band rejected, with Franceschi saying that they would "probably end up killing each other" if they could not interact with other people.

According to Franceschi, only one track was substantially changed and Richardson suggested minor corrections to others, such as adding another chorus or an additional bar in a verse.

[22][23] Though later Heyler grew wary of this, Franceschi reasoned without their friends' visits, the band would hate the recording process; "it was that shit".

[23][22] During the third week of recording, Franceschi took a conference call with the band's manager, who told him Richardson was unhappy with the way the sessions were progressing.

[24] Following this, Franceschi learned that his tweet about seeing Noel Gallagher in the studio had accidentally leaked the news that a former Oasis member was recording a solo album.

[14] Strings and brass, which were arranged and conducted by Jeremy Rubolino, were recorded at EastWest Studios in Los Angeles by Jorge Velasco with assistant engineer Jeff Ellis.

[39] Author Neil Daniels, in his book You Me at Six – Never Hold an Underdog Down (2015), wrote that they "wanted to be taken out of the teen-friendly pop-punk scene, quite literally.

With Sinners Never Sleep, the band focussed on showcasing a wide variety of sounds, incorporating new instrumentation such as strings, horns, pianos and samples into their work.

[43] They wanted to avoid continuing the American-esque topics that were prevalent on their preceding two albums, alongside the usual themes of parting and going after girls.

[42] The riff of "Time Is Money", which had been compared to the work of Pendulum with an From Autumn to Ashes-like breakdown, was written while the band were recording Hold Me Down but was left off at Franceschi's suggestion.

[33][44][42] As part of the marketing, You Me at Six's website featured a timer that counted down across five days,[40] and on 1 August 2011, Sinners Never Sleep was announced for release in two months' time, with its track listing and artwork being revealed.

[55] The video, directed by Tim Matthia,[56] was released on 30 August 2011; it features each of the band members being manhandled police officers, cut with footage of them performing.

[57][58] The song was released as an extended play (EP) on 23 September with instrumental and acoustic versions of "Loverboy" and "Moon Child" as additional tracks.

[60] It was accompanied by the behind-the-scenes documentary Bite My Tongue, which chronicles You Me at Six's history from their first practice session to the recording of Sinners Never Sleep.

[80] To promote Sinners Never Sleep's release, the band did a series of in-store performances and signing events, and went on a UK tour, with support from Deaf Havana and Lower Than Atlantis.

[89] You Me at Six embarked on a headlining UK tour in March and April 2012; the Ireland dates were pushed back as Franceschi suffered from tonsillitis.

The Aquarian Weekly writer Marissa Savino praised the record for being "both catchy and meaningful" with its "twelve relatable tracks, each set to an infectious beat".

[38] In a review for Hot Press, Edwin McFee called it the band's best effort that "benefit[s] hugely by adding a little spice to the sugar", referring to the inclusion of Sykes and McCall.

[104] Gigwise's Will Lavin commended the band for "stay[ing] consistent through thick and thin", and releasing "both head nodding bangers and thought provoking gems".

[101] Big Cheese reviewer Rob Mair said the band stuck to the "tried and tested" but "succeed in pushing the boundaries at the edges" rather than completely revamping their sound.

[28] Punknews.org staff member Sloane Daley called it "a pretty damn good pop rock record" but said it lacks decent lyrics.

[35] BBC Music's Alistair Lawrence said the release tries to focus on both the future and the past simultaneously, making it "destined to sound a bit like a (frequently awkward) transition".

[105] AllMusic reviewer Jon O'Brien found the release "much more convincing when it plays to its melodic strengths" rather than "pandering to the Kerrang!
