Miami-based folk singer Keith Johns flipped the script on the traditional folkie origin story. Just two years ago, he was a physicist working at a carbon dating lab by day and writing and recording music by night. His efforts resulted in the 2014 EP Maps and Plans, and by the time he released his full-length album Grateful Fool in 2016, he'd quit his day job for an earnest shot at a music career. Johns has earned a faithful audience around town with solo acoustic and band performances at festivals, and particularly through his ongoing First Fridays residency at the Wynwood Yard, where he performs original music and invites other local folk artists to showcase their talents. He's also earned a sizable streaming audience outside of Miami with his lyricism, which leans as heavily on the transcendentalist and naturalist writings of Henry David Thoreau as it does on the scientific spiritualism of Carl Sagan. "Come, won't you look at the stars in the night/And the people on the street/They're one and the same and I'm certain in time/They'll switch places and repeat," he sings on "Isn't It Grand?" "How bland, if it always went as planned," he continues. If anyone can rhapsodize on the joys of surrendering to life's unexpected turns, it's this physicist-turned-folk singer.
