Bluegrass, in its purest form and in various mutations, seems to be seeping its way into a lot of popular music these days. I think it’s great, both because I love the music itself and because it helps to ensure that an important strain of American culture and the instruments and players that helped create it survive for at least another generation or two.
In fact, listening to Mumford and Sons, I think its preservation is pretty much guaranteed, given that these boys are from London. No, not London, Kentucky. The one in England, with the queen and the prince about to marry his princess and all that.
