Billboard’s Country Up-And-Comer Mack Geiger Went From Student Paramedic to Hot 100 Hitmaker in Eight Months: ‘It’s Been a Trip’
The Australia-based country singer-songwriter is earning a chart breakthrough with his song "String By."
When Mack Geiger was a child, he showed an early interest in country music. At a preschool dress-up day, he dressed up as Alan Jackson, a Country Music Hall of Famer. Geiger's upbringing on his family's cattle ranch in Queensland, Australia, influenced his work ethic and dedication to his craft. After growing up around cattle and working on ranches, Geiger released his breakthrough single "String By" in October 2025, which reached No. 48 on Billboard's Country Airplay chart and earned him a debut on the Hot 100.
He has since played high-profile events, including the Grand Ole Opry and CMA Fest, and embarked on a U.S. headline tour. Geiger's work ethic and Australian bush-inspired songs have helped him achieve success in the country music scene.
