A Death Metal combo out of Täby, masterminded by Johan Edlund. TREBLINKA was the forerunner of leading Alt-Gothic Metal band TIAMAT, a band that has evolved chameleon like with each successive release. Less tastefully known in their formative years as TREBLINKA (during which time vocalist Johan Edlund also pursued his side project GENERAL SURGERY), the Swedish quartet adopted the title of the Sumerian goddess of chaos and mythical planet TIAMAT. The band has evolved from a derivative Speed Metal / Death act to a more substantial stance in offering aggression with adventurous Progressive variances.

As TREBLINKA the band consisted of vocalist/guitarist Johan Hedlund ("Lucifer Hellslaughter"), bassist Klas Wistedt, guitarist Stefan Lagergren ("Emetic") and drummer Andreas Holmberg ("Najse Auschwitzer"). This unit released the 1988 demo 'Crawling In Vomits' and follow up tape 'The Sign Of The Pentagram' in 1989. Also emerging that year would be the ' Severe Abomination' EP.

Upon taking the TIAMAT moniker the group issued debut album 'Sumerian Cry' through CMFT Productions in 1990.

TREBLINKA veterans Stefan Lagergren and Jörgen Thullberg both featured in the 2009 combo MR. DEATH, a Stockholm based "straightforward, brutal, old-school Death Metal" band also featuring Jocke Lindström, from DIGRESSION ASSASSINS, on lead vocals, Alex Stjärnfeldt, of OCEANLIFT, EDWARD and DCLXVI, on second guitar, and Jonas Ohlsson, from VOID and MASSIVE, on drums.
