Piece of Mind is the fourth studio album by English heavy metal band Iron Maiden.

[4] Included in the liner notes is a slightly altered version of a passage from the Book of Revelation, which reads, And God shall wipe away all tears from their eyes; and there shall be no more Death.

[5]The actual text (from Chapter 21, Verse 4) is nearly identical, except that it reads, "neither shall there be any more pain" rather than "brain", which was added as a pun on the album's title.

Lyrically, the album largely reflects the group's literary interests, such as "To Tame a Land", inspired by Frank Herbert's 1965 science fiction novel Dune; [6] "Sun and Steel", based on the life of samurai Miyamoto Musashi[7] and its title taken from Yukio Mishima's 1968 essay Sun and Steel; "Still Life", influenced by Ramsey Campbell's 1964 short story "The Inhabitant of the Lake",[7] and "The Trooper", inspired by Alfred, Lord Tennyson's "The Charge of the Light Brigade" (1854).

[6] On top of this, "Revelations", written by Dickinson,[10] includes lines from G. K. Chesterton's hymn "O God of Earth and Altar",[11] while the remainder of the song is influenced by Aleister Crowley.

[6] At the beginning of the sixth track, "Still Life", the band included a hidden message which could only be understood by playing the song backwards.

According to McBrain, "We were sick and tired of being labelled as Devil worshippers and all this bollocks by these fucking morons in the States, so we thought, 'Right, you want to take the piss?

published a poll of the greatest metal albums of all time, with Piece of Mind ranking No.1 and The Number of the Beast at No.2.

[4] Reviews were mostly positive, with Sputnikmusic hailing it "easily an album that belongs in your collection" (although they argue that "the likes of Powerslave [1984], Somewhere in Time [1986], and Brave New World [2000] would overtake it"[14]).

[9] In a mixed review from Rolling Stone, "Both Piece of Mind and Powerslave proceed in kind, albeit with diminished melodic interest..."[12] It was ranked No.

[24] In 2010, Maiden uniteD, featuring lead singer Damian Wilson, released an all-acoustic reinterpretation of the album entitled Mind the Acoustic Pieces.
