Open Air debuted on Halloween 2011 at the frequency formerly occupied by the legendary KCFR, and the Colorado Public Radio-affiliated station has since established itself as one of the most free-spirited stations around. Its popularity is due not only to its programming, but also to its on-air personalities. The best among them is Alisha Sweeney, whose morning show features a well-curated mix of alternative, indie and classic artists, from Feist and New Order to David Bowie and Brian Eno, that would appeal to anyone. And her banter between songs is just as charming as her selections.
