For the second time on “Music Raygun,” our topic for this episode is no topic at all. It’s our first sequel episode as we bring you another grab bag of videos. We’re looking at an assortment of our favorite clips that more or less defy categorization. That means Elvis, Chakha Khan, Captain Beefheart and Anita O’Day all in one podcast. And that’s just to name a few of the wild artists we visit in this episode. Wesley Snipes is in there somewhere too. It’s a pod-boy bouillabaisse.
