Tiamat is a metal band that formed in Stockholm, Sweden in 1987.
Initially, the band played straightforward black metal under the name Treblinka. After having recorded the album Sumerian Cry in 1989, vocalist/guitarist Johan Edlund and bassist Jörgen Thullberg parted ways with the other two founding members, and subsequently changed the name to Tiamat. The Sumerian Cry album included re-recorded Treblinka songs and was released in June 1990.
After the debut, Edlund's leadership would modify the band's style with influences ranging from Black Sabbath, Mercyful Fate, Candlemass, Pink Floyd and King Crimson, with Sumerian lyrical themes. Polish guitarist Waldemar Sorychta would produce and contribute instrumentation to many of the band's albums, as well as those by Tiamat's own tour and labelmates, including Moonspell, Rotting Christ, Lacuna Coil and Samael.
1994's critically acclaimed Wildhoney mixed raw vocals, slow guitar riffs and synthesizer sounds which sounded different from other extreme metal bands active at that time. An almost continuous forty-minute piece of music, Wildhoney led to the band's appearances at the Dynamo and Wacken Open Air heavy metal festivals in 1995. The group would play a second gig at Dynamo two years later.
