Synonymous with the high polish of Def Leppard and the filthy boogie of AC/DC during their 80s career peaks, Robert John ‘Mutt’ Lange (the nickname comes from his childhood) has appropriately been described as the James Cameron of rock producers. But delve deeper into his CV and you might be surprised to find that the reclusive South African-born producer began his career with R&B pub rockers Graham Parker and The Rumour, The Motors, prog-pop outfit City Boy, country bands Clover and Outlaws, and blues rockers Savoy Brown.
As much technical prowess and skill that any good producer might possess, what separates a good producer from a great producer is the same as what makes a great manager: one that encourages, inspires, and develops those around them to perform even better. A talented bass player and a trained singer, Mutt is an accomplished musician in his own right – perfectly placed to understand and respect the mindset of his protégés. As such, Def Leppard and AC/DC took him to their hearts. For both bands, Mutt produced the best-selling albums of their careers following their respective tragedies.
Def Leppard bassist Rick Savage simply considers Mutt a genius. Guitarist Phil Collen credits him with improving his playing when he joined during the recording of Pyromania. “When I met Mutt, my playing changed – as a producer he makes you play a lot better,” said Phil. “He improved my playing 100 per cent. He does that to everyone he works with.”
During the recording of Back In Black, Brian Johnson was encouraged by Mutt to sing even higher than he thought attainable, pushing him to the very height of his ability and insisting on precision – as evidenced on opener Hells Bells. “I knew never I could sustain notes like that,” said Beano of his ’DC debut.
A teetotaller known for putting in long hours – a dedicated work ethic not to every musician’s taste – Lange’s attitude to producing is to cultivate, improve and polish a piece of music over and over until it’s faultless. It’s a meticulous and painstaking attitude to work and undoubtedly the hallmark of a perfectionist.
Notoriously private, Mutt is only known to have taken part in one interview in his entire career – for the BBC’s 1989 Def Leppard documentary, Rock of Ages. “We would just take each song and try to raise it to the standard of a rock classic,” Mutt said of working with Def Leppard on Hysteria. “We would just hone and hone and hone until the music itself was right.”
