Longwood University professor Chris Kjorness' article "Show Me Your License, Daddy-O: How New York City tried to regulate bebop to death" was published in the February 2013 edition of Reason magazine. Kjorness explores how New York City forced musicians to be licensed to perform in city nightclubs and how losing one's card—as happened to famed saxophonist Charlie Parker—impacted the development of musicians and the bebop style.
