Since arriving years ago from his hometown of Toronto, Frank Evans has put a stamp on Nashville’s storied bluegrass scene like few others in such a short time. Deft and original on both Scruggs-style bluegrass and old-time clawhammer playing, he’s been a versatile and in-demand sideman. Now he’s getting set to release his first solo album as a leader, full of original instrumentals and creatively unearthed songs from the deep catalog of roots music.
