Singer-songwriter Kelsey Waldon tweeted upon news of Bell’s passing: “I have been heartbroken to hear about the passing of Luke Bell. A bunch of us met in Nashville when we were so young and obsessed with country music – those years were so formative. He was extremely gifted & special. Go listen to Luke today. Rest In Peace now, old friend.”
