Which band released the 1983 album 'Piece of Mind'?

Iron Maiden released the 1983 album Piece of Mind. It was the band's fourth studio album and one of the records that established their expansive, melodic approach to heavy metal.

Piece of Mind includes "The Trooper," "Revelations," and "Flight of Icarus." Its songs draw on subjects including war, literature, mythology, and history. The album also introduced drummer Nicko McBrain, who replaced Clive Burr and became a major part of Iron Maiden's classic lineup.

The title is a pun on the phrase "peace of mind." Judas Priest, Saxon, and Motörhead were fellow British heavy metal acts, but none released an album titled Piece of Mind.
