Moses began his musical journey at the age of six after becoming interested in the mandolin. He soon developed a lasting passion for making music. He started to hone his skills playing in his family's band as a child. Since then, he's toured with bands such as Blue Moon Rising, NewFound Road, Band of Ruhks, The Dan Tyminski Band and Ricky Skaggs & Kentucky Thunder. In his two-year stint with Tyminski, he realized an early dream of playing the Grand Ole Opry for the first time and recorded the 2009 IBMA Album of the Year and Grammy nominated album, Wheels.
He has appeared on stage or in studio with such diverse artists as Alison Krauss, Del McCoury, Garth Brooks, Emmylou Harris, Brad Paisley, Joe Diffie, Jerry Douglas, Vince Gill, Bruce Hornsby, Peter Frampton, Rosanne Cash, Dwight Yoakam and Barry Gibb.
In 2017, Justin married acclaimed mandolin player, singer and songwriter, Sierra Hull. The two now often perform together as a duo, showcasing their instrumental prowess and close vocal harmonies. These days Moses may be seen almost anywhere and with almost anyone. But he is performing regularly with multi-award winning band The Gibson Brothers.
