Forever the Sickest Kids (sometimes abbreviated as FTSK) is an American pop punk band from Dallas, Texas.

The band first signed with Universal Motown Records and released its debut album, Underdog Alma Mater, on April 29, 2008.

From Burleson, Texas, Jonathan Cook and Kyle Burns were in a band together in high school, Good Day Josif.

[2] About the same time in Hurst, Texas, Marc Stewart and Kent Garrison were in a band together called Triumph Over Tragedy,[3] with friends from their high school.

Burns and Stewart are step-brothers,[5] resulting in Good Day Josif and Triumph Over Tragedy sharing a practice space in their parents' garage.

In 2004, upon the break up of Good Day Josif and Triumph over Tragedy, Cook, Stewart and Burns formed the band the Flipside, along with their friend Chris Hill.

[6] Craig Calloway (from Triumph over Tragedy) was added to the Flipside's lineup, and Garrison replaced Chris Hill on bass guitar.

[5] Around the same time, Committed broke up, and childhood friends Austin Bello and Caleb Turman formed an acoustic/electronic project called Been Bradley.

[5] Days after the formation of Forever the Sickest Kids, Cook accidentally spent $350 that the band did not have on PureVolume to receive a front-page placement of a song.

[19] In support of the album, the band went on the 2008 Alternative Press tour along with All Time Low, The Rocket Summer, The Matches and Sonny.

[28] The deluxe edition of Underdog Alma Mater was released on July 7, 2009 and features the original twelve songs from the album, seventeen additional tracks that were mainly demos and acoustics from the band's earlier days, and a DVD that included recorded live shows of the band and music videos.

[35] In February, the compilation album Punk Goes Classic Rock was released, with the band covering "Crazy Train" by Ozzy Osbourne.

[36] In March, a version of "What Do You Want from Me" with slight editing of the lyrics was used in the ending credits of the film Diary of a Wimpy Kid.

[43] The band then supported The Downtown Fiction, All Time Low, Boys Like Girls, Third Eye Blind, and LMFAO on The Bamboozle Roadshow 2010.

The band went on "The Summer Camp for the Dope Awesome Kids Tour", which featured The Scene Aesthetic, The Ready Set, A Cursive Memory and Phone Calls from Home.

[46] The group began working on their second studio album with producers David Bendeth and John Bender in 2010 in New Jersey, New York, Irving and Fort Worth.

[33] They explained this decision was made because as they had gone into the studio with producer Bendeth, they continued to quickly write more than five songs for the EP and decided to release a full-length album instead.

[48] On January 10, 2011, two months before the release of the self-titled album, Garrison posted on his blog that he was leaving the band, stating that he wanted to "pursue other opportunities.

[16] The band headlined the "Spring Break Your Heart" tour with Breathe Carolina, We Are the In Crowd, This Century, Tonight Alive and Before Their Eyes from March to April 2011.

[68] The band performed at the NFL Play 60 Kids' Day Experience in New Orleans at the Ernest N. Morial Convention Center, ahead of the Super Bowl XLVII.

[69] On February 21, in an interview with idobi Radio, Cook revealed that the album would consist of twelve songs and would be released on June 25.

[71] On April 25, a preview of "Chin Up Kid" was released and the album's cover art and track listing were revealed, with its title confirmed as J.A.C.K.

[84][85] Turman and Andradi formed a band called TEAM*, along with Jay Vilardi of the Almost, and Bryan Donahue, formerly of Boys Like Girls.

[87] On August 20, 2015, the band posted on their Facebook page that they were "very much alive and well" and they had been taking the time to focus on their personal lives.

"[91] On April 29, 2018, the band celebrated the 10 year anniversary of Underdog Alma Mater by releasing limited vinyl editions of the album.

[5] Many of the band's songs feature synthesizers and have dance and electronic based influences, along with the piano and keyboard often being included.

The band mainly has positive, upbeat sounds in its songs, which are typically structured with pop based hooks, both electronic and regular drum beats, and catchy guitar riffs that still maintain rock and punk elements to the music.

Cook generally sings with a powerful, screeching voice and frequently ranges from a low to high pitch.

Turman is known for taking the lead in the band's acoustic songs, such as "Coffee Break" and "Forever Girl", due to having a much softer voice than Cook and Bello.

Blink-182, Fall Out Boy, Weezer, Bowling for Soup, New Found Glory, and Fountains of Wayne have served as some of the main influences for the band.
