Gabber Modus Operandi was accidentally founded by Kasimyn and Ican Harem following their fad staging at an underground punk concert in Denpasar. After some DJ- and MC-ing, Kasimyn began producing tracks for the duo using the smallest musical instrument: the Mini Synth Teenage Engineering OP-1, while Ican Harem provides vocals and joke-filled improvisation. Their experimentation began with a healthy obsession for the energy and intensity of jathilan, gabber, dangdut koplo, Chicago footwork, grindcore and noise music.
