I was thinking about the Folk Revival in the US and possible causes. It occurred to me that, if you date it as starting in the fifties, it isn’t a coincidence that it would happen as the development of the interstate highways system and the internal movement following WW II. I theorize that bringing more people into contact with unfamiliar local culture and traditions would lead to an interest in documenting or preserving those traditions.
Before I thought about it I would have said that the interest in local culture was a response to the rise of a more national culture — radio, movies, etc. I think that’s part of the story, but, upon examination, that transition started in the 20s and 30s, which leads me to think that transportation and the mixing and movement of people during and after the war were more important.
Comments? It sounds reasonable to me, but it’s just inference.
