The quintessential arena rock producer, Robert John "Mutt" Lange rose to fame on the strength of the blockbuster albums he recorded for 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 blockbuster smash 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, and resumed the partnership for 1983's Pyromania, which officially broke the band in America. Lange co-wrote two of the album's smash hits, "Photograph" and "Rock of Ages," and also authored hits for other artists during that same period, including Loverboy's "Lovin' Every Minute of It" and Huey Lewis & the News' "Do You Believe in Love."
