Powerslave" is the title track of the fifth album by heavy metal band Iron Maiden. It tells of the rise and fall of the mythological Eygptian Chaos God, Set, to the hands of the Sky God, Horus. (Into the abyss I'll fall-The eye of Horus). He was then sent to the God of the afterlife, Osiris, who was reborn. (Enter the risen Osiris-Risen again). He just can't believe that this has happened to him after he built such an empire, and doesn't see it fair that he, a God, must die.
The use of Egyptian imagery, such as the eye of Horus, and allusions to mythology is allegorical for vocalist Bruce Dickinson's spiteful outlook on the music industry, and how their greed and disrespect for talent leads to their own demise. On live performances of this song, Dickinson wears a theatrical mask. The first guitar solo is played by Dave Murray, the second one by Adrian Smith and the third by Dave Murray.
