Piece of Mind is the fourth studio album by British heavy metal band Iron Maiden. It was originally released in 1983 (see 1983 in music) on EMI, and on Capitol in the US; it was reissued later on Sanctuary/Columbia Records. It was the first album to feature drummer Nicko McBrain, who had recently left the Paris-based band Trust. "The Trooper" remains as one of the most popular songs in the band's history, and has been included in the set list of all of the band's concert tours since the album's release. During the Blaze Bayley era, it was used as the closing song for the lineup's tours.
