Inclement weather has forced a rare snow day for Houston Baptist University. As I sit, drinking some hot chocolate and reading, I can listen to music at reference volume instead of the quiet “background music” that office etiquette requires. Suddenly this morning, I recognized that the opening track of Captain Beefheart album “Safe as Milk” is actually an instantiation of “Rollin’ and Tumblin'” but with different words. Here was a song I had heard in many forms, now refreshed and remade. But it was still the blues classic I loved. It occurred to me that Rollin’ and Tumblin’ was a universal.
