Horsehead were an Australian hard rock band which formed in late 1991 by Scott Kingman on guitar (ex-Cattletruck), Cameron McKenzie on guitar, Andy McLean on vocals (both ex-21 Guns), Mick Vallance on bass guitar (Serious Young Insects, Boom Crash Opera) and Craig Waugh on drums (Uncanny X-Men). They toured nationally and internationally as well as supporting United States group, Metallica, on the Australian leg of their April 1998 tour. The band issued three albums, Horsehead (1993), Onism (1996) and Goodbye Mothership (1999) before disbanding in 2000. According to Australian rock music historian, Ian McFarlane, their style of "stadium rock mixed a Led Zeppelinesque bottom-end kick with gut-thumping Faith No More-styled riffs. Nothing subtle or innovative, but everything delivered with great force and conviction".
