Jean-Baptiste Cardineau (he/him) is a Franco-American mandolin player, singer and songwriter who manifests his unique musical and lyrical vision via a well-spring of various early styles of music. His unique "Nouveau-Traditional" style has already unleashed the heavy picking artillery on some of the worlds biggest stages and won him the 2025 Freshgrass Award in mandolin and a full ride scholarship to Berklee College of Music where he studied Jazz, Classical music, and various ethic styles while his spontaneous Bluegrass playing became synthesized with the early innovators on the mandolin.​​

JB was raised in the French Alps and moved to the Wild West as a teenager. He started playing fingerstyle guitar at eight years old prior to moving to the States in 2017, where he picked up his grandmother's 200 year old Breton mandolin. With a musical and lyrical vision, his voracious desire to find the Cardineau sound is the driving force behind his musical modus operandi.
