Charles Robert "Charlie" Simpson (born 7 June 1985) is an English musician. He was the youngest member of multi-BRIT Award-winning band Busted, and is the lead vocalist, guitarist and co-lyricist in alternative rock band Fightstar. AllMusic has noted that Simpson is "perhaps the only pop star to ever make a convincing transition from fresh-faced pop band to an authentic alternative rock frontman." Simpson is a multi-instrumentalist, skilled at playing the guitar, keyboard, piano and drums.
Following three successful studio albums and subsequent tours, Fightstar initiated an extended hiatus in 2010, allowing Simpson to focus on his solo career. Simpson released his debut EP When We Were Lions on Christmas Day 2010. His debut full-length album entitled Young Pilgrim was released on 15 August 2011. Simpson signed to Nusic Sounds record label in 2011 and his second solo album Long Road Home was released on 4 August 2014.
