Answer by taking a quote from the following article:

Bring Me the Horizon, often known by the acronym BMTH, are a British rock band from Sheffield, South Yorkshire. Formed in 2004, the group now consists of vocalist Oliver Sykes, guitarist Lee Malia, bassist Matt Kean, drummer Matt Nicholls and keyboardist Jordan Fish. They are signed to RCA Records globally and Columbia Records exclusively in the United States. The style of their early work, including their debut album Count Your Blessings, has been described primarily as deathcore, but they started to adopt a more eclectic style of metalcore on later albums.

Bring Me the Horizon recorded their second studio album, Suicide Season, in Sweden with producer Fredrik Nordstrom. He was unimpressed with their first album and was initially absent from the recording sessions unless he needed to be there. Nordstrom later heard the new sound they were experimenting with during a recording session and became very involved in the record. It was promoted virally in the weeks before its release with the promotional tag line "September is Suicide Season." To promote Suicide Season the band embarked on their first headline tour of the United States, as well as appearing at the 2008 Warped Tour. In May 2008, Bring Me the Horizon was the main supporting band on I Killed the Prom Queen's farewell Australian tour with The Ghost Inside and The Red Shore. Suicide Season was released on 18 September 2008 in the United States on Epitaph and on 29 September in Europe through Visible Noise. In 2009, Bring Me the Horizon attended the 2009 Kerrang! Tour alongside Black Tide, Dir En Grey, In Case of Fire and Mindless Self Indulgence. They also joined Thursday, Cancer Bats, Four Year Strong and Pierce the Veil on the North American leg of the 2009 Taste of Chaos tour from February to April after the tour's organizer Kevin Lyman offered them the slot. During the Taste of Chaos tour in March of that year, guitarist Curtis Ward left the band. His relationship with the band had deteriorated as his stage performances were poor. He was abusive to audiences during the Taste of Chaos tour, and had contributed little to the writing of Suicide Season. Another reason for his departure was the worsening tinnitus in his one functioning ear. Ward was born deaf in one ear and admitted playing in the band worsened the ringing in his other ear to such a degree that he was unable to sleep at night. Ward offered to perform the rest of the tour dates, which the band rejected and instead asked their guitar technician, Dean Rowbotham, to substitute for him for the remaining performances. Lee Malia noted that Ward's departure helped improve everyone's mood as he had been very negative. Within a week of the tour finishing, Sykes began talking to Jona Weinhofen, at the time the guitarist of Bleeding Through. The band knew of him from his work with his former band I Killed the Prom Queen, and he was asked to join them. Ward has since worked on the TV show Top Gear, and has occasionally performed on stage with Bring Me The Horizon, playing "Pray For Plagues", most notably at Wembley Arena in 2015. In 2016, it was announced that Ward had joined the band Counting Days. In November 2009, Bring Me the Horizon released a remixed version of Suicide Season, titled Suicide Season: Cut Up! Musicians and producers featured on the album include: Ben Weinman, Skrillex, L'Amour La Morgue, Utah Saints and Shawn Crahan. Musically, the album incorporates many genres including: electronica, drum and bass, hip-hop and dubstep. The dubstep style of the record has been acknowledged in tracks by Tek-One and Skrillex while the hip-hop elements are found in Travis McCoy's remix of "Chelsea Smile".

Who produced the album?
producer Fredrik Nordstrom.
