One of the last great rock stations, KSHE in St. Louis, has a 4-hour show on Sunday mornings called KSHE Klassics. Nothing but deep tracks and forgotten gems. It’s free on their app.
There are still small out let’s out there ..
But for the most part. Radio has become a homogeneous single corporate entity. Playing the exact play list on multiple stations.
In the Boston area. We now have 2 independents. Playing a really good mix. They seem to be pretty small. And relatively new.
Hopefully, they succeed . And that spreads. You know they are small, as all of their ads are local independent businesses.
