In 1989, Jason walked into the Music Emporium (then in Cambridge, MA) and saw a Gibson Mandobass on top of a display case and it was love at first sight. In addition to being the founder and principal arranger for Ecco, Jason regularly performs on Mandobass with the L’Esperance Mandolin Ensemble and has participated in the East Coast Mandolin Orchestra. An excerpt of his composition The Gibbous Suite was featured on the Moth Radio Hour in 2022.

In addition to being the founder and principal arranger for the Ecco Mandolin Ensemble, Jason is an avid purveyor of all things strings, and when not resettling instruments, he regularly accompanies his wife and her group of Gaelic singers on guitar in addition to occasionally resuscitating his folk-funk band, Bean.
