By Night is a Swedish metalcore band from Falkenberg, formed in 1999 by guitarists André Gonzales and Simon Wien, along with drummer Per Quarnström. The trio had previously played together in Predicted Conspiracy but sought to explore a different musical direction. The band was completed with the addition of bassist Henrik Persson and vocalist Christoffer Andersson. By Night released their first two demos, By Night (2000) and Derelict (2001), before replacing Andersson with Adrian Westin in 2002. This lineup secured a deal with Lifeforce Records following the release of another demo. Their debut album, Burn the Flags, was released in 2005 and marked their breakthrough moment. The band toured extensively with acts such as The Destiny Program, Deadsoil, Disbelief, Ektomorf, and Betzefer. In 2006, they released their second album, A New Shape of Desperation. By Night played at the With Full Force Festival in June 2007.
