Sometimes while I'm puttering around my craft studio, I like to listen to KCEA over the internet. This is one of the better things to come out of the California Bay Area lately. Its a station that plays old Big Band and swing music from the20's through the 40's. If you live in the Atherton/Menlo Park area, you can get it over the old FM radio waves, as well.
Oh yes. Blissfully free of commercials, except for the odd nostalgic piece thrown in for atmosphere.
