Believers in backmasking think they can hear "Hail Satan" and other messages to Satan in a song by Aerosmith that was released as part of which album ?
Hail Satan "Hail Satan", sometimes expressed in a Latinized version as "Ave Satanas" (or "Ave Satana"), is an expression used by some Satanists to show their dedication to Satan, but has also been used for the purpose of comedy or satire. Believers in backmasking think they can hear "Hail Satan" and other messages to Satan in some songs played in reverse, such as "Walk This Way" by Aerosmith. The variation "Ave Satani", though grammatically incorrect, is sometimes used, likely originating from its use by Jerry Goldsmith in his theme music to "The Omen".
Angel of Death (Slayer song) "Angel of Death" is the opening track on the American thrash metal band Slayer's 1986 album "Reign in Blood". The lyrics and music were written by guitarist Jeff Hanneman. They detail the Nazi physician Josef Mengele's human experiments at the Auschwitz concentration camp during World War II.
