Gretchen Wilson may not be one of country music’s top female vocalists any longer. No, she’s transcended the genre, in a way Alison Krauss did her’s years ago. Except Wilson’s not getting any of the recognition, until maybe now. ‘One Good Friend’ is a brilliant ballad about the meaning of friendship. However it’s perhaps too professional to fit between the stars on modern country radio, a problem Krauss and more recently Vince Gill know very well.
