From time to time, I have posted music that I first heard on KCEA-FM, always with a link to KCEA, the radio station of the Menlo-Atherton, California, school district.
KCEA is currently moving its studio. It’s still broadcasting, but the stream is not available.
If you want music that swings and miss KCEA, try the 1920s Radio Network, which happens to be affiliated with my local NPR stations.
I have more links to music that swings, but those two are the best. If you are interested in the others, just ask or go to Icecast or Shoutcast.
