know?" Release and reception Preceded by the single "Flight of Icarus" on 28 April, Piece of Mind was released on 28 May 1983. It peaked at No. 3 in the UK and spent eighteen weeks on the chart. In North America, the album became the band's highest charting thus far, peaking at No.14 in the Billboard 200. By July, Piece of Mind was certified gold by the RIAA, rising up to platinum status in 1986. In 1995, the album achieved platinum status in the UK. In 1983, Kerrang! 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. 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"). AllMusic described it as "essential for anyone with even the most basic interest in heavy metal", although "the second half dips a bit from the first". In a mixed review from Rolling Stone, "Both Piece of Mind and Powerslave proceed in kind, albeit with diminished melodic interest..." It was ranked No. 21 on IGN's list of the top 25 metal albums in 2007. The supporting tour titled the World Piece Tour opened at Hull City Hall on 2 May. The tour concluded on 18 December, and its 139 concerts included a televised performance at Westfalenhalle in Dortmund.
