Bullet for My Valentine, often abbreviated as BFMV, are a Welsh heavy metal band from Bridgend, formed in 1998. The band is currently composed of Matthew Tuck (lead vocals, rhythm guitar), Michael Paget (lead guitar, backing vocals), Jason Bowld (drums) and Jamie Mathias (bass guitar). Former members include Michael Thomas, Jason James and Nick Crandle; the latter were on bass. They were formed under the name Jeff Killed John and started their music career by covering songs by Metallica and Nirvana.

On 28 January 2011, Michael Paget stated that the group had already drawn proportions for the next studio album and will sound a lot like Fever. He followed-along with stating that the band plans to have the songs for it written within 2011 and will begin recording the album by the end of the year. A couple tracks left from the Fever sessions might be re-done, re-arranged and re-recorded for the new record. The band played at Uproar Festival 2011, after which they began writing material for a fourth studio album.  On 7 October, RCA Music Group announced it was disbanding Jive Records along with Arista Records and J Records. With the shutdown, the band (and all other artists previously signed to these three labels) will release their future material (including their next studio album) on the RCA Records brand. Also in October, frontman Matt Tuck announced that he will be working on a new side project which he has described as "metal as fuck", influenced by bands such as Pantera and Slipknot. On 1 May 2012, it was revealed that the project will be called AxeWound, and will feature Liam Cormier, Mike Kingswood, Joe Copcutt and Jason Bowld. In May 2012, it was announced that Bullet for My Valentine would be playing at the South African music festival Oppikoppi, as well as a once-off gig in Cape Town alongside Seether and Enter Shikari. They were slated to play in the country for the Coke Zero Fest of 2009, but pulled out at the last minute to record Fever. It was confirmed on 6 August that the final recording session of the band's fourth studio record was complete, and that the album would be out sometime in late 2012. Later that month on the 17th, the second line-up for the Australian music festival Soundwave was announced, containing Bullet for My Valentine.  Bullet for My Valentine released the track "Temper Temper" on 25 November in the UK and 30 October worldwide across all digital providers. The song was debuted live by the band on Monday 22 October at BBC Radio 1's Rock Week where they performed at Maida Vale studios. It was announced the day prior to the performance that the band's fourth studio album would also be named Temper Temper. The release date was confirmed to be the 12 February 2013.  The band began touring in support of Temper Temper on 10 February 2013, and finished the tour on 3 November 2013. The tenth show of the tour, held at Birmingham's O2 Academy, was filmed by music video website Moshcam.com.
