Early Life

Lange was born on November 11, 1948 in Mufulira, Northern Rhodesia (now Zambia) and given the name Robert John Lange. He was raised in Durban, South Africa by his parents. His mother was German and came from a well-to-do family while his father was a South African mining engineer. Lange was nicknamed Mutt from an early age and grew up constantly listening to music. He was a particular fan of country music in his early life. Lange attended Belfast High School in what is now Mpumalanga province. While there, he started a band in which he played rhythm guitar and sang harmonies.

From 1966 to 1967, Lange completed his required national service. After finishing, he decided to focus on pursuing a career in music.


In 1969, Lange formed the band Sound Reason along with James Borthwick, a South African television, film, and stage actor.

Beginning in 1976, he started working with the U.K. band, City Boy, and produced five of their albums between then and 1979. In 1978, he produced "Rat Trap" for The Boomtown Rats, which topped the charts in the U.K. He also produced Ipswich Town's FA Cup final single called "Ipswich Get That Goal." He agreed to do this because the team had a South Africa-born player named Colin Viljoen.

In July of 1979, he produced AC/DC's hard rock album, "Highway to Hell," which went to number eight on the U.K. charts. He continued working with AC/DC by producing two more of their albums, including "Back in Black" in 1990 which became one of the best-selling albums of all time. He also worked on albums for Foreigner and Def Leppard. He specifically worked on "High 'n' Dry," "Pyromania," "Hysteria," and "Adrenalize." He took a break from working with Def Leppard for a few years but returned in 1999 for their "Euphoria" album. His work with Def Leppard was depicted in the 2001 television film, "Hysteria – The Def Leppard Story," in which Anthony Michael Hall portrayed Lange.

In addition to working with AC/DC and Def Leppard, Lange also worked with artists like The Cars, Romeo's Daughter, and Billy Ocean throughout the 1980s.

In the 1990s, Lange started working with Bryan Adams and produced his album, "Waking Up the Neighbours." He co-wrote the song, "Everything I Do, I Do It For You," which was featured in the Kevin Costner film, "Robin Hood: Prince of Thieves." The song went to the top of the U.K. singles chart and holds the record for longest number of consecutive weeks in the number one spot. He also produced albums and tracks for Michael Bolton, Stevie Vann, The Backstreet Boys, and Shania Twain in the 1990s.

In the 2000s, he produced albums and tracks for Shania Twain, Muse, Maroon 5, Celine Dion, Lady Gaga, and Britney Spears, among other artists. Throughout his career, two of the albums he has produced have won Grammy Awards in addition to three of his produced songs.

The couple were married shortly after in December of 1993. In August of 2001, they had a song together named Eja.
