Alison Krauss is one of my favorites.
I like AK too... hope she’s appearing as a respect for the institution of the Presidency, and White House, and not to honor its present occupants.
One of my favorites, as well. Alison Krauss seems to have a very wide appeal. It is entirely possible that that the Obamas actually are fans of her music.
Of course, they could just be inviting AKUS because she grew up in Illinois.
She seems to be the real deal. Reference fellow freepers, http://www.freerepublic.com/focus/f-news/1305407/posts
