Do you ever wonder why St. Louis Public Radio covers a particular concert but not an art show opening on the same night? Or a certain play but not a simultaneous music festival? Editors are instrumental in these kinds of decisions. And we’ve got a new editor for our arts and culture team, who’s come to town with some new ideas. David Cazares (pronounced CAH-sar-ehs ) comes to us from Minnesota Public Radio, where he served as a web editor and music writer with an emphasis on jazz.
