Edited sentence: Although the Satanic backmasking controversy involved mainly classic rock songs whose authors denied any intent to promote Satanism, backmasking has been admittedly used by heavy metal bands to insert Satanic messages in their lyrics or imagery.Cradle of Filth, another band which has employed Satanic imagery, released a song entitled "Dinner at Deviant's Palace", consisting almost entirely of ambient sounds and a reversed reading of the Lord's Prayer (a backwards reading of the Lord's Prayer is reportedly a major part of the Black Mass).For example, thrash metal band Slayer included at the start of the band's 1985 album Hell Awaits a deep backmasked voice chanting "Join Us" over and over at increasing volumes ().However, Slayer vocalist Tom Araya states that the band's use of Satanic imagery was "solely for effect".Still, the majority of bands that use Satanic imagery have not been shown to be Satanists, and many bands have utilized Satanic imagery solely for commercial reasons
