Seminal Australian thrash metal band Mortal Sin grew out of the western suburbs of Sydney in the early 1980s and by 1987 had become the country's most important extreme metal act. With the line-up of Campbell, Eftichiou, Maurer, Paul Carwana (guitar) and Keith Krstin (guitar), Mortal Sin rose to the top of a scene which at the time offered little competition. With their Metallica-inspired sound the band became firm favourites amongst the Sydney metal fraternity and in 1987 issued the raw but inspired Mayhemic Destruction album which found favour offshore and won them an international record deal. Shortly after it was released Krstin was replaced by ex-Slaughter Lord member Mick Burke and the band solidified their reputation by supporting Metallica in 1989 shortly after releasing Face of Despair, which while technically superior seemed lacking in really good songs. Shortly afterward there was more internal turmoil and Campbell left the band. Steve Hughes (also ex-Slaughter Lord) replaced him and Mortal Sin toured Europe with Testament and Faith No More, but following a disastrous benefit show in Sydney which the band organised that eventuated in the venue being damaged by the lunatic fringe in the audience, Maurer expressed displeasure with the line-up and left. Mortal Sin effectively ceased to be at this point, but continued precariously. In 1991 Eftichiou recorded and gigged with a completely different Mortal Sin line-up which brought the ire of the rest of the former members who laid claim to the name. Despite a legal dispute, an album and single were released before it ground to a halt. Eftichiou went on to join the woeful Who's Guilty. Campbell went on to White Trash and then joined up with Hoffman in Sydney death metal stalwarts Grungeon for most of the 1990s. Mortal Sin reformed in late 1996 with four of the original members in Maurer, Campbell, Eftichiou, and Carwana along with Hoffman. Carwana's stay was brief before he was replaced by Scerri (ex-This Thing, White Trash, numerous others). A mini-album was released which featured re-recordings of early songs, reworked demos and one or two new originals and the band embarked on a disastrous national headlining tour which suffered from poor attendances and the volatility of individual band members. Eftichiou was ousted shortly afterwards and replaced for the band's Metal for the Brain appearance by Chook from Tscabeze. With Jason Thorncraft from Headlifter finally taking Eftichiou's place, Mortal Sin seemed reasonably content for sometime to work up from the bottom again, but the strain began to show and in September 1998 the band played its last show. Scerri later formed Daredevil and now plays in a hardcore band called The Blasting Process. Campbell continues as the booker of the Forest Inn in Sydney as well as playing in the band Temtris.
