A self-made singer/songwriter, Matt Wertz spent years creating soulful, feel-good pop music on his own terms. Nashville — a city that doubled as his muse and adopted hometown — always played a big role in that creation process. It was the place where Wertz wrote his songs, the place he recorded his albums, the place he’d return after touring the country with songwriters like Jason Mraz, Maroon 5, Parachute and Gavin DeGraw.
