Mike Chapman, Garth Brooks' longtime studio bassist, has died. He was 63 years old, and had been battling "an aggressive form of cancer," according to No Treble.

An Alabama native, Chapman began his career as a studio musician in Muscle Shoals, Ala., then made the move to Nashville. He played bass on more than 30 No. 1 hits, according to All Access, including all of Brooks' studio records, as part of the country superstar's band, the G Men. Additionally, Chapman worked with LeAnn Rimes, Brooks & Dunn, George Jones, Trisha Yearwood, Joe Diffie and more; collectively, the recordings on which he played have sold more than 170 million copies.

Although Chapman played bass with Brooks in the studio, he was not on the road with the icon. As part of the G Men, he was inducted into the Musicians Hall of Fame on June 5, just a few days before his death.

Chapman passed away on Monday (June 13), and a celebration of life was held on Friday (June 17) in Franklin, Tenn., with a private burial scheduled for June 20. He leaves behind a wife, Connie; two sons, Lee and Clinton; a daughter, Allison; and a grandson, Wyatt; he is also survived by his sister Faye. Donations in his name may be made to the Musicians Hall of Fame and Museum or Meals for Health & Healing.
