Taking Back Sunday is an American rock band from Long Island, New York. The band was formed by guitarist Eddie Reyes in 1999. The band's members are Adam Lazzara (lead vocals), John Nolan (lead guitar, keyboards, vocals), Eddie Reyes (rhythm guitar), Shaun Cooper (bass guitar) and Mark O'Connell (drums). The band has released three studio albums with various past members Fred Mascherino (guitar, vocals), Matthew Rubano (bass guitar), and Matthew Fazzi (guitar, keyboards, vocals).

On June 10, 2005, it was announced that the band had signed with major label Warner Bros. Records and would begin recording their third album later in 2005. That month, the group contributed "Error: Operator" to the video-game adaption of Fantastic Four, and it was later added to the film's soundtrack as well.  On September 21, 2005, it was announced that Taking Back Sunday had begun recording their third album with Eric Valentine. The group chose Valentine because he had produced Queens of the Stone Age's Songs for the Deaf (2002) and Third Eye Blind's self-titled album (1997). On April 25, 2006, Taking Back Sunday released their third album, entitled Louder Now, on Warner Bros. Records. The members' comments on the album reflected the dramatic change the band had undergone in the two years since their last release. Matt Rubano noted that the move to a major label was not something the band took lightly, but it was a move that made sense given the band's tumultuous past. Lazzara stated that fans seemed to feel their live shows had more energy than their recordings, and that Louder Now brought more of that across.  Taking Back Sunday received mainstream exposure by appearing on the late night talk shows The Tonight Show with Jay Leno, Jimmy Kimmel Live!, and Late Night with Conan O'Brien, as well as the teen drama Degrassi: The Next Generation in an episode entitled "What's It Feel Like To Be A Ghost?".  In December 2006, the band released its first documentary, Louder Now: PartOne, featuring behind-the-scenes tour footage and four live concerts. Following months of touring to support Louder Now, Taking Back Sunday appeared in the American leg of Live Earth on July 7, 2007. During the summer of 2007, Taking Back Sunday was also a part of Linkin Park's Projekt Revolution tour, along with My Chemical Romance, HIM, and several other bands.  On October 30, 2006, the band's former record label, Victory Records, released Notes from the Past, which featured four songs from Tell All Your Friends, six songs from Where You Want To Be, and two B-sides: The Ballad of Sal Villanueva and Your Own Disaster ('04 mix). The band then released Louder Now: Part Two on November 20, 2007, a DVD of unreleased live concert footage from their show at Long Beach Arena in Long Beach, California, which included special features such as the video for "Twenty-Twenty Surgery", made to be released in Europe. The DVD was packaged with a companion CD featuring eight live tracks, two B-sides that were previously unreleased in America, and a special "Twelve Days of Christmas" track. In 2007, the band contributed the song "What's It Feel Like to Be a Ghost?" to the soundtrack for the science fiction action film Transformers, although the song did not appear in the film.
