Their 2005 debut EP, They Liked You Better When You Were Dead, was released in 2005 and was a critical success.
The band released their debut studio album, Grand Unification, the following year; Kerrang! editor Paul Brannigan called it "one of the best British rock albums of the last decade". Fightstar received a nomination for Best British Band at the 2006 Kerrang! Awards before releasing their second album, One Day Son, This Will All Be Yours, in 2007. A compilation album including B-sides and rarities, Alternate Endings, was released the following year.
