DEMENTOR started its existence as a three piece band in August 1988. The first line up was: Roman Lukac-guitar, Lubos Gazdik-bass and his brother Roman-drums. At the beginning they produced typical thrash/death metal influenced by early bands such as VENOM, Slayer, Possessed, Kreator, Celtic Frost , Death. They realised some rehearsal recordings till 1991. The band does not spread this stuff because of dissatisfaction with the result.
