<P> In 2010, the band contributed the track "My Obsession" to the God of War: Blood & Metal soundtrack . The band was later added as late replacement to 2010's Download Festival in June, after original sub-headliner, Wolfmother could not attend as scheduled . Afterward, Killswitch Engage took a break from the road, and its members pursued other interests . Adam Dutkiewicz formed the band Times of Grace with Leach and released the debut album "The Hymn of a Broken Man" on January 18, 2011 . Along with Dutkiewicz and Leach, Times of Grace added Joel Stroetzel to their tour lineup . Justin Foley provided the drum tracking for the band Unearth on their album "Darkness in the Light", released on July 5, 2011 . Foley also traveled with the band for their 2011 summer tour . D'Antonio started the hardcore band Death Ray Vision, with Shadows Fall vocalist Brian Fair and former Killswitch Engage guitarist Pete Cortese . </P> <P> In an interview with FTC, Gun Shy Assassin, Mike D'Antonio had stated that the band was currently in the works for a sixth studio album . D'Antonio stated, "Currently, everyone is individually writing demos for the next Killswitch Engage record . There is no release date yet, but I would assume it will be out early 2012 ." Adam Dutkiewicz followed that up with a statement on the Killswitch Engage Facebook, saying "YO! Its Adam D! We're about to begin writing our new record . Thanks to all of our fans for waiting so friggin' patiently...now let's turn on the "riff faucet" and RAGE!" On December 1, 2011, Mike D'Antonio posted online that Killswitch Engage should be entering the studio around February / March 2012 to record their sixth album expected around summer 2012 . He also stated that the band had eight demos finished for the new record . </P> <P> On January 4, 2012, the band announced via the band's official website, along with their other official sources, that Howard Jones had left the band after his nine - year membership with them . In the statement, the band did not disclose the reason for this decision out of respect for Jones, but simply thanked him for his nine years with the band and wished him well, as well as thanking the fans for their support as they began the search for a new lead singer; Jones later explained he departed the band to manage his type 2 diabetes which was worsened by a hectic touring lifestyle . Soon after the announcement of Jones's departure, rumors began that Phil Labonte of All That Remains would officially take over lead vocals due to his previous history with the band, although Labonte quickly dispelled the rumor . Many vocalists were considered in the search for a new one for the band . The band's search for a new singer concluded in February with the announcement that original lead vocalist Jesse Leach would return to the band, as the band felt that Leach's energy, as well as his overall comfort and command of both the old and new material, made him the clear choice during auditions . Following Leach's return, the band continued to the process of recording their new album and touring . On April 22, 2012, the band performed Leach's first show since 2002 at the New England Metal and Hardcore Fest . </P> <P> On June 20, 2012, the demo version of a new song titled "This Is Confrontation" was leaked on YouTube .

The band performed this song live, confirming the song's title "No End in Sight". Not long after the album was confirmed, the song was streamed publicly again . In October 2012, with Jesse back at the helm, Killswitch Engage announced they would be celebrating the ten year anniversary of their seminal album Alive or Just Breathing with a US Tour through November / December 2012, in which the band played the album live in its entirety .
