Almost four decades since it’s domestic release, Karen Marks’ 1981 single Cold Café has finally reaped it’s deserved international credit to become one of Australia’s most recognised minimal wave recordings. Efficient Space now showcases the Melbourne artist’s brief but entire discography, including two previously unheard demos, all produced with experimental synthesist Ash Wednesday (The Metronomes, Modern Jazz, Thealonian Music). A rarity in the then male dominated industry, Marks found her footing in music, first through rock journalism and then in band management. Formally of Adelaide, newly arrived synth-punks JAB (Johnny Crash, Ash Wednesday and Bodhan X) approached her for representation, subsequently contributing tracks to seminal 1978 snapshot Lethal Weapons and playing the Crystal Ballroom’s opening night.
