Christian music pioneer Norman Miller died of cancer Dec. 3. He was 69.

Founder of Nashville-based Proper Management, Miller worked in Christian music for 50 years, founding the groups ZOEgirl, Avalon, Jump5 and PureNRG, and managing tours for Casting Crowns, Nichole Nordeman, TobyMac, Michael W. Smith, Newsboys, Sandi Patty, Steven Curtis Chapman and many other artists.

On Casting Crowns' Facebook page, the band said Miller "was a hero for Christian music and us."

"Norman lived a life fueled by his passion for his faith, his deep love for his family and his care for his friends," the group said. "He also was renowned for his indelible impact on the Christian music industry. Norman was a creative visionary who was constantly focused on increasing the quality of compelling and engaging ministry. His legacy will continue to effect countless lives through the eternal message of the artists he dearly loved and faithfully served.

"Norman's loss is immeasurable and we are all humbled, honored and blessed to have known him as a respected leader and a loyal friend," Casting Crowns added. "We ask that you lift Norman's wife and children in your prayers during this difficult time. Norman was our close friend and manager for 10 years. We will miss him dearly."

A native of the U.K., Miller played in Christian bands there during his late teens and early 20s, starting his own record label in 1970. It was later acquired by Word Records.

Miller became the executive director of the Word Europe label from 1973 to 1983, as well as promoting and producing tours throughout Europe featuring pioneering Christian artists such as Larry Norman, Andrae Crouch and 2nd Chapter of Acts.

In 1983, Miller moved to the United States, and started managing artists and producing tours. Miller is survived by his wife, Debbie, and two children. A memorial service will be held Dec. 10 at Brentwood Baptist Church in Brentwood, Tenn.
