In Flames is a Swedish heavy metal band, formed by guitarist Jesper Strömblad in Gothenburg in 1990. Their lineup has changed several times, with vocalist Anders Fridén and guitarist Björn Gelotte being the only consistent members since 1995. Alongside At the Gates and Dark Tranquillity, In Flames has pioneered the genres known as Swedish death metal and melodic death metal, and as of 2008, has sold over two million records worldwide.

Dark Tranquillity is a Swedish melodic death metal band from Gothenburg. They are considered one of the pioneering acts of the Gothenburg metal scene, which also includes bands such as In Flames and At the Gates - regarded as the Gothenburg fathers in the film entitled Out of Nothing: A DT Documentary released by Century Media, which was filmed in their home town in April 2009. After a nearly three-decade long collaboration of four founding members frequent lineup changes between 2016 and 2021 have left only vocalist Mikael Stanne as an original member, together with long-time keyboardist Martin Brändström.
