Fightstar is a British post-hardcore band from London, formed in 2003.

The band’s line-up comprises lead vocalist, guitarist and keyboardist Charlie Simpson, guitarist and vocalist Alex Westaway, bassist Dan Haigh and drummer Omar Abidi. Although generally considered a post-hardcore band, Fightstar are also known to implement metal, progressive, alternative rock and acoustic elements into their sound.

During the band’s initial emergence, they were faced with much skepticism due to Simpson’s former pop career. However, they began to receive positive reactions to early live shows and their debut EP, They Liked You Better When You Were Dead (2005), was a critical success. Since then, their four studio albums have obtained top 40 chartings and critical praise.
