Fireside is a Grammis Award-winning rock band that formed in the Swedish Hardcore scene in the early 1990s.

 In 2000, with the release of "Elite", the band took a more experimental approach to rock, but 2003's "All You Had" saw the band return to Emo rock/Pop punk.

 Taking influence from such pop punk acts as Blink-182, Saves the Day and Taking Back Sunday, Man Overboard played a brand of upbeat and poppy pop punk with the emotion of 90s emo acts such as The Promise Ring.
 The band was signed to Rise Records.
 They are well known for their motto within the pop punk scene to "Defend Pop Punk".
 On January 28, 2016 they announced a hiatus on their official website.

 The band was featured in the low-budget horror film "Trans-American Killer" in 2005.
 Singer Dirk Vermin opened Pussykat Tattoo in 1999; the shop, Vermin, and bassist Ruckus are currently featured in the A&E program "Bad Ink".

 The initial US leg was sponsored by "Rockstar" energy drink, with the band supported by Set Your Goals, The Wonder Years, Man Overboard, and This Time Next Year.
 The band wanted to showcase young talent from within the pop punk scene, following in the footsteps of bands such as Less Than Jake, Blink-182 and Green Day, who had in turn helped them out by offering support roles early in their career.
 It was announced on 1 August 2011 that the tour would commence on 6 October in Santa Cruz, California, running through 20 November in San Diego following the release of the band's seventh studio album "Radiosurgery".
 AbsolutePunk ran an exclusive competition on their website, with five pairs of free tickets available for the tour including a meet-and-greet with the band back stage.
