Adrenalize is the fifth studio album by English rock band Def Leppard and originally came out on March 30, 1992 through Mercury Records. It was the band's first album following the death of guitarist Steve Clark in 1991; most songs had already been partially demoed before his death but were subsequently re-recorded solo by Phil Collen. The album was produced by the band together with longtime engineer Mike Shipley, with Mutt Lange serving as executive producer. Vivian Campbell joined the band as new guitarist in April 1992, after recording had finished, and appears in most of the album's music videos. Adrenalize includes the singles Let's Get Rocked, Make Love Like a Man and Have You Ever Needed Someone So Bad, and sold more than seven million copies worldwide.
