Kendell Marvel has spent the majority of his 25-year music career behind the scenes of Nashville’s music machine. He’s penned hits for big names like Chris Stapleton and George Strait, and has picked up a handful of Grammys for his efforts. But a few years back, Marvel, now 52, got an itch to focus on writing and performing his own songs, and as of September, he’ll have a trio of records to his name. While each has its own personality, they all offer stories told by a mature purveyor of country music.
