The problem with folk? It's so folky. Catie Curtis wallops folk in its anemic gut by bringing a little bit of pop fun to the party. Written while she was becoming a first-time parent, the crisp and driving Long Night Moon is personal, and it's mellow, and it's touching. But it's also some of the year's most engaging acoustic music. And if you're a fan of Grey's Anatomy, you'll already recognize "Lo, How a Rose E'er Blooming" from the season 2 soundtrack. Come watch the rose bloom.
