Dark Tranquillity are a Swedish melodic death metal band from Gothenburg, formed in 1989. They are considered one of the pioneering acts of the Gothenburg metal scene, which also includes bands such as At the Gates and In Flames. After a nearly three-decade long collaboration of four founding members frequent lineup changes between 2015-2021 have left only vocalist Mikael Stanne as an original member, together with long-time keyboardist Martin Brändström. The current lineup of the band consists of Stanne (vocals), Brandstrom, Johan Reinholdz, Peter Lyse Karmak, Christian Jansson (bass), and Joakim Strandberg Nilsson (drums).
