WBEZ the last surviving all jazz FM station operating in Chicago recently announced that within a year they will change format - to talk radio. Obviously the world needs more talk radio. I still have one college radio station with full time jazz programming, but after that, it's up to my collection and what little live stuff is happening around town.
Chicago, which once had a justified claim to being the center of jazz, has now rejected it. Change isn't always for the better.
