If you've heard local blues artist Hans Olson playing on your favorite network-television procedural drama, or the catchy guitar rhythms of CooBee Coo over a swanky men's clothing commercial, that's the work of the licensing gurus at Fervor Records. When the Sunnyslope-based label isn't putting Arizona music in your ears as you binge the most recent season of your favorite Netflix show, it's releasing new music from The Pistoleros and Fayuca, or compiling our state's musical history into one of its collections. One of its latest offerings, Mid-Century Sounds: Deep Cuts From the Desert, celebrates the work of Phoenix studio owner Floyd Ramsey, who recorded Waylon Jennings and legendary guitarist Duane Eddy.
