Growing up in Eastern Kentucky, Rigsby discovered bluegrass music early on. At age 5, Rigsby learned to sing from a 1959 tape of Ralph Stanley singing
"Hills of Home" and "Little Maggie." Rigsby befriended two of Ralph Stanley's Clinch Mountain Boys: Ricky Skaggs (Rigsby's cousin) and Keith Whitley.
Rigsby learned guitar at age 12, then fiddle, dulcimer, and mandolin. While attending Morehead State University, Rigsby was a member of TruGrass, which
included Johnny Lewis (banjo) and Tim Gilliam (guitar), with Rigsby on mandolin.
