In this week’s back-by-popular-demand re-airing, we’re joined by popular young bluegrass artist Billy Strings. Whether he’s performing as a solo artist or with his band, the reaction to Billy tends to come in two varieties: “Who is this guy?” and “That kid can play!” Also with us is the progressive instrumental group, the Jon Stickley Trio. Plus, we’ll have a conversation with our eChievement Award winner of the week who’s founded a group that’s transforming abandoned paved places into urban gardens, parks and more.
