Robert John 'Mutt' Lange PhotoThe quintessential arena-rock producer, Robert John "Mutt" Lange rose to fame on the strength of blockbuster albums from acts including Def Leppard, AC/DC and Foreigner. His career began in 1976, when he produced Graham Parker's Heat Treatment as well as the self-titled debut from City Boy, the first in a series of collaborations with the group. Lange's breakthrough followed three years later with AC/DC's seminal Highway to Hell. He reunited with the group a year later for the classic Back in Black, followed in 1981 by Foreigner's mega-hit 4, which earned him a Grammy nomination as Producer of the Year. That same year, he also helmed Def Leppard's High 'n' Dry, his first collaboration with the band; 1983's Pyromania made them stars, with Lange co-writing smash hits including "Photograph" and "Rock of Ages." Other hits he authored from the same period included Loverboy's "Lovin' Every Minute of It" and Huey Lewis & the News' "Do You Believe in Love."

After his next monster hit, the Cars' 1984 album Heartbeat City, Lange reunited with AC/DC on 1986's Who Made Who before returning to the Def Leppard camp for 1987's Hysteria, one of the best-selling rock albums of all time. With Billy Ocean's Tear Down These Walls, Lange moved into R&B, scoring a smash single with "Get Outta My Dreams, Get Into My Car." A long layoff preceded the release of his next production, Bryan Adams' 1991 LP Waking Up the Neighbours, which generated the mega-hit "(Everything I Do) I Do It for You." Lange continued working with greater infrequency as the decade progressed - after Def Leppard's disappointing 1992 effort Adrenalize, he returned to hitmaking form a year later with Michael Bolton's The One Thing. His next project was new wife Shania Twain's breakthrough 1995 smash The Woman in Me; the couple reunited in 1997 for Come on Over. ~ Jason Ankeny, All Music Guide
