The song was later released as part of their début album, Making Dens, albeit in a slightly altered, re-recorded form.
Mark Moore of Contactmusic.com positively reviewed the single version, describing it as having a "fresh sound" and exemplifying the quality of the bands on the 2006 iteration of the NME ShockWaves tour.
