Toward the end of the '90s, Scandinavian death metal -- or at least one branch of it -- began to evolve into a more accessible amalgamation of death metal intensity, a bit of progressive metal experimentation, and more traditional late-'70s/early-'80s British metal, with its catchy, groove-oriented riffs and twin-guitar lead lines. Although the style was hardly confined to one place, there was an especially fertile scene centered in the Swedish city of Gothenburg, and Dark Tranquillity were one of its most prominent practitioners. Formed in 1989, Dark Tranquillity honed their chops for a few years and debuted on record in 1993 with the album Skydancer; their lineup consisted of vocalist Anders Freiden, guitarists Niklas Sundin and Mikael Stanne, bassist Martin Hendriksson, and drummer Anders Jivarp. The band shuffled its membership for the 1995 follow-up EP Of Chaos and Eternal Night; upon Freiden's departure, Stanne took over lead vocals, and was replaced on guitar by Fredrik Johansson. This lineup remained intact for the full-length The Gallery issued later that year, which helped begin to build an international fan base.
