Sam Bush, originally from Bowling Green, began his musical career at 15 when he won the first of his three National Junior Fiddle Championships (he also plays mandolin). He made his recording debut in 1969, at age 17. At 19, he and some friends formed a group that would rock the bluegrass world. Over the next 18 years, that group—New Grass Revival—would be so successful and innovative that fans and critics began to refer to their “new” bluegrass sound as “newgrass.”
