Blow Up was released on 17 November 2003 by the record label Modular.[3][4] "Beat On / Beat Off" was released to radio as a single and received airplay on Triple J.[4]
Australian Music Online described the release as "a dirty dark soundtrack to sweaty clubs that reeked of sex and sweat and [...] was electro pop delivered with rock'n'roll aggression."[3] Jose Solis of PopMatters wrote that the EP "announced the arrival of an act that was unafraid to get down and dirty when it came to mixing rock beats with pulsating electronic tempo, something that has become the norm as EDM and electronica become the most popular music genres around".[5]
