Hysteria is the fourth studio album by English rock band Def Leppard, released on 3 August 1987 through Mercury Records and reissued on 1 January 2000. It is the band's best-selling album to date, selling over 20 million copies worldwide, including 12 million in the US, and spawning seven hit singles. The album charted at #1 on both the Billboard 200 and the UK Albums Chart.[1][2] Hysteria was produced by Robert John "Mutt" Lange. The title of the album was thought up by drummer Rick Allen, referring to his 1984 auto accident and the ensuing worldwide media coverage surrounding it. It is also the last album to feature guitarist Steve Clark before his death, although songs co-written by him would appear in the band's next album, Adrenalize. The album is the follow-up to the band's 1983 breakthrough Pyromania. Hysteria's creation took over three years and was plagued by delays, including the aftermath of the 31 December 1984 car accident that cost Allen his left arm. Subsequent to the album's release, Def Leppard published a book entitled Animal Instinct: The Def Leppard Story, written by Rolling Stone magazine Senior Editor David Fricke, on the three-year recording process of Hysteria and the tough times the band endured through the mid-1980s. Hysteria has earned critical acclaim from a number of sources. In 1988 Q magazine readers voted it as the 98th Greatest Album of All Time, while in 2004, the album was ranked at #472 on Rolling Stone's list of the 500 Greatest Albums of All Time.
