Dark Tranquillity
Initially formed as a side project by Ceremonial Oath bassist Jesper Strömblad in 1990, the group's first full lineup in 1993 also featured guitarist Glenn Ljungström and bassist Johan Larsson. As the band were without an official vocalist, their 1994 debut "Lunar Strain" featured contributions from Dark Tranquillity frontman Mikael Stanne, as well as several guest musicians. The 1995 EP "Subterranean" featured vocals by Dawn's Henke Forss, as well as drums by Daniel Erlandsson of Eucharist and Anders Jivarp of Dark Tranquillity. Around the time of the EP's release, Björn Gelotte joined In Flames as the band's first official drummer, and a short time later Anders Fridén was brought in from Dark Tranquillity as the group's first official vocalist.
