I have NO opinion about this group, and know next to nothing about the subgenre of British folk-or-maybe-it's-not-folk music. But here's my input:

Someone up there among the earlier posts seemed to imply that heartfelt, soulful, expressive singing that may be less that perfectly pitched is acceptable only when practiced by "source singers," but not on the part of current-day young artists. I beg to differ! Musical expression of any kind is valid insofar as listeners hear it as meaningful ~ whatever the listener might know about the performers' age or background is completely irrelevant. (If it's OK for some dead singer to be "ragged but right," it's OK for you or me as well!)

I'd also like to note that I found the explanations of the break-up very interesting and appropriate. Enough information, but not too much, and absolutely no self-justiying posturing and no finger-pointing. Whatever their merits as musicians, these young women all seem to know how to behave as human beings.
