Charlie Judge has been the wizard behind the keys—as well as a high-in-demand arranger—in Nashville for decades. His synthesizers add a sweet breeze to Keith Urban’s “Blue Ain’t Your Color” and his bold and bright piano on Florida Georgia Line’s “H.O.L.Y.” sets the scene for a touching savior story. He’s at work on both the ivories and synths to build Stevie Nicks’ “Has Anyone Ever Written Anything for You” into a melancholy dream.
