We know a classic when we see one, hear one, feel one. Forgive me for sounding like a Cadillac ad voice over or something, but seriously, sometimes there’s just an ineffable sense that something beautiful and meaningful is unfolding. And while we can’t pull that off every single week, we try to put the pieces in place for a chemical reaction. And this week it happened. There was combustion and satisfaction. We ranged across the country and across roots music terrain with acoustic grand master Tony Furtado from Portland, OR, Texas-raised songwriter Curtis McMurtry, Colorado polyethnic joyride Gipsy Moon and veteran John Jorgenson’s remarkable bluegrass band.
