In Flames is a Swedish heavy metal band, formed by guitarist Jesper Strömblad in Gothenburg in 1990. At the Gates, Dark Tranquillity, and In Flames are the only remaining bands responsible for developing the genres known as Swedish death metal and melodic death metal.
During the band's early years, In Flames had a varying group of musicians recording with them, including many session musicians. By the release of Colony (1999) the group had established a stable lineup. Their sixth studio album Reroute to Remain (2002) showed the band moving toward a newer style of music that moved further away from melodic death metal and closer to alternative metal. This decision was criticized by fans of the group's heavier metal sound; however, it increased the band's mainstream audience and bolstered their album sales. As of 2008, In Flames has sold over two million records worldwide.
