Two years later we made the move to our present address, 35 The Headrow, where we have remained ever since. The song was the first song which Fish "really got his teeth into" which is shown in the heavy use of electronica. I was struggling with addiction and my relationship with the band before this record was fractured and I felt the only way I could apologise for my actions was to knuckle down and pour everything into a record.

On 3 November 2012, the band invited fans and the Drop Dead Clothing team to enter Angelic Studios to record the gang vocals for Sempiternal. It is the first album to feature former Worship keyboardist Jordan Fish and the first with guitarist Lee Malia playing both lead and rhythm components. It stems from the Latin word " sempiternus" (a concatenation of root " semper" and suffix " aeternum").It smashed preconceptions with it’s trailblazing release and was both forward-thinking and innovative. Written and recorded throughout 2012, Sempiternal showed the band pull diverse influences from nu metal, electronic music, ambient music and pop.

Sykes explained that while There Is a Hell examined mannerisms such as dealing with great amounts of depression, Sempiternal examines learning how to deal with that stress. AllMusic gave the album a positive review saying, "Bring Me the Horizon have been working slowly but surely to refine their sound for years now, and with Sempiternal, it feels like their patience and hard work are finally beginning to pay dividends. He also commented on how the album would explore similar territory as their third album There Is a Hell. The sound of the album is seen as still being as aggressive as their typical work but having choruses that are "made for arenas" [35] and a lot of electronic-influenced hooks.Sykes said he admires Date's production work shown on White Pony and Chocolate Starfish and the Hot Dog Flavored Water. Afterward, they had intentions to issue a remix extended play consisting of electronica remixes of tracks off the album, all done by British electronic producer Draper, aiming for a tentative January 2012 release. It didn't work out as well for us this time because we liked that before as we were always touring, and we needed somewhere quiet to go.

At the end of this video it was revealed that the album was scheduled to be released on 29 April 2013. This was due to the fact that the ground covered by the album gave room for further experimentation. The introductory song "Can You Feel My Heart" was a musical experiment which helped sculpt the style of Sempiternal.His role developed over the course of writing the album as he was initially there to be instructed by the band in what to do but he slowly started to have more say in the album's writing. This record brought our band closer than ever and for that it will always have a special place in my heart. It took us so long to get into the writing process this time because we had that massive tour, and we hadn't written for so long. Lee Malia described the song as having a more Suicide Season inspired sound [38] and having a Glassjaw-influenced chorus. This marked the end of the Sempiternal-focused era of Bring Me the Horizon and the break they will use to make a new album.
