Since 1987, Diesel has played on several albums by well-known Australian rock singer and brother-in-law, Jimmy Barnes. Although better known as a singer-songwriter and guitarist, Diesel is also competent on bass guitar, drums, percussion and keyboards; and has also produced an album by Richard Clapton and one by Vika and Linda Bull. He has won five ARIA Music Awards with three for 'Best Male Artist' in 1993, 1994 and 1995.
Diesel was born in 1966 in Fall River, Massachusetts, United States, and emigrated to Australia with his family, in November 1971. His father, Henry Bertram Lizotte (born 19 June 1929), and his mother, Theresa Rita (née Morin, born 18 January 1930) were parents of Jeannine, Bruce, Michael, Laura, Donna, Brian and Mark. They settled in Perth, Western Australia, where he later had a job pouring petrol—an experience that provided inspiration for his music. Henry was a professional saxophonist performing in the US and Australia, Diesel and his siblings were surrounded by music from an early age. While his siblings became teachers, Diesel eventually settled on electric guitar as his main instrument. He later recalled a time in Year 8 (c. 1979) at Scarborough Senior High School when he decided on a musical career: "I was trying to get my head around algebra [...] and suddenly I thought: 'Hang on, I don't have to do this. I can play music as a job!'".
Diesel had worked for the Raid unit for five of his seven years, and was the first Raid dog killed on duty. He was due to retire the next spring. On 18 November 2015, Diesel was killed in a shootout with suspected terrorists in the Saint-Denis area of Paris, while searching for suspects involved in the November 2015 Paris attacks. During the raid, which was in response to the November 2015 Paris attacks, the dog had been sent in to clear rooms following a cessation of gunfire from the suspects. The first room was empty, but after he entered a second room, the gunfire started once more. He died of multiple gunshot wounds. Following the raid, some media reports claimed that Diesel had been killed by a female suicide bomber. This was later shown to have been incorrect as there was no female bomber. Diesel, "was saluted for his bravery by the Paris police chiefs who told Le Parisien[...] that dog almost certainly saved his handler’s life during the raid."
