Mark Moffatt, a mainstay Nashville producer and guitarist, died on Friday (Sept. 6) after a year-plus-long battle with pancreatic cancer. He was 74 years old.

According to a statement from his team, Moffatt contributed more tracks to the Australian Performing Right Assocation (APRA)’s Top 30 Songs of All Time list than any other one producer.

He was a veteran engineer, writer and musician in Nashville, but paid special attention to developing the careers of artists who hailed from his home country of Australia. Perhaps the most famous of those was Keith Urban who has credited Moffatt’s impact on his career transition from Australian celebrity to more mainstream country music success in the U.S. after he moved to Nashville.

For the last two decades of his life, Moffatt worked from the vantage point of the Americana Music Association (AMA) to bridge international divides. He was a founding board member of the Americana Music Foundation and served three terms as the AMA’s Board President in his efforts to find common ground between music in the U.S. and international contributions.

Though much of his career focus landed in the country genre, Moffatt also worked with rock artists throughout his life. He formed a band called Kilo with Australian rock singer John “Sawanee” Swan, and together, they were finishing up an album at the time of Moffatt’s death.

Moffatt is survived by his wife Lindsey, step-daughter Dana and son Geordie, as well as two granddaughters and extended family. A celebration of his life will take place, with details to follow.
