A block of music on Public Radio International, hosted by John Diliberto. It started in 1989. I'm not sure when I first heard it, but probably sometime in the early 90s. It airs Saturday nights at 11 on my local public radio station, but it's been years since I've listened to it (because I don't really listen to radio, anymore). Anyway, it plays mellow music, very ambient and soothing, so it's something I used to like to have on when I was going to sleep. But please don't confuse that with "boring," or anything like that. It really is cool, and worth listening to the whole program just for the fun of it (and not as a soporific).
