The Radio Kitchen is essential. The Chef doesn't update very often but there are archives you can lose yourself in if you're interested in what American radio sounded like before it became one big Clear Channel bore. The most recent posts, contained recordings taken from the radio during a road trip from Detroit to New Orleans in 1988 capture the sound of an America that's familiar but already mostly gone and the writing captures the long lost thrill of being in the middle of nowhere at 4am, turning on the radio and hearing Lighting Hopkins on the AM dial.... Lovely stuff.
