Adrenalize

Adrenalize is the fifth studio album by British rock band Def Leppard, released in 1992. The album was the first by the band following the 1991 death of guitarist Steve Clark. It was produced by Mike Shipley and Def Leppard, with Robert John "Mutt" Lange as executive producer. The album charted at #1 on The Billboard 200 and #1 on the UK Albums Chart.
At the end of the Hysteria World Tour in October 1988, Def Leppard vowed to the press that their next album would not take another four years to be released, and quickly reconvened weeks later to start work. However, Steve Clark's alcoholism was taking a turn for the worse. Whereas touring had kept him sober onstage, offstage his condition was beginning to affect his work in the studio. In addition, Mutt Lange was unavailable to return as producer as he was working with Canadian rocker Bryan Adams on Waking Up the Neighbours.
The band chose to produce the album themselves. Steve's problems did not help to advance progress and in fact, was starting to set them back. In late 1989, Clark was found unconscious in a gutter in Minneapolis, Minnesota. He was immediately sent to rehab, and band members (along with Lange) started attending confrontational therapy to attempt to shame him into defeating his addictions. In a desperate move to help their friend, guitar tech Malvin Mortimer was assigned to keep a 24-hour watch on Clark; according to Joe Elliott, it was a difficult task.
None of this proved to be fruitful, and in August 1990 the band granted Clark a six-month leave of absence. While it was hoped that this break would free him of any stresses, the band seemed resigned to the fact that they could no longer do anything for Clark.
On 8 January 1991, Steve Clark was found dead in his London home by his girlfriend Janie Dean. The coroner's report revealed that Clark had died of an accidental mix of alcohol with painkillers and anti-depressants that led to compression of the brain stem.
After a short period of uncertainty about the band's future, the remaining members decided to resume work on the album. Former Lange engineer Mike Shipley was hired as co-producer, while Lange maintained a minor role via phone calls and demos sent to him.
A search for Clark's replacement was held off until after the completion of the album, and recording sessions progressed quickly in the year that followed. On 31 March 1992, Adrenalize was released worldwide. While some reviews were favorable (Rolling Stone magazine awarded it 4 out of 5 stars), many critics attacked the album for being formulaic and too similar to Hysteria. Although Clark had died prior to the release of the album and did not participate in the recording process, nearly every song on the album was at least co-written by him.
Further complicating matters, Adrenalize was released during the time when grunge and alternative rock bands were killing off "glam/pop metal" bands. Nonetheless, Adrenalize debuted at the number one position in both the UK and the US (quickly going triple platinum there). The album has sold over 7 million copies worldwide. The album was dedicated to the memory of Steve Clark.
Former Dio and Whitesnake guitarist Vivian Campbell, a longtime friend of the band, was brought in as the newest member in April 1992. He appears in all promotional videos for the album's singles (except "Let's Get Rocked"), despite not playing on the album.
A Deluxe Edition of Adrenalize, which was released in 2009, includes a digitally remastered version of the album, plus a Bonus CD containing b-sides from the album's singles.
