radio virtually blacklisting the band – they received little airplay prior to the emergence of public radio stations (such as Triple J and 3RRR) in the mid-1970s. Australian musicologist, Ian McFarlane, described the album's cover as "controversial" in that it depicted "a mournful, blood-soaked face peering through the eye socket of a skull" while buyers were advised to "Play this album LOUD".
