Mary Chapin Carpenter, “Sometimes Just The Sky” (Thirty Tigers)- Multiple Grammy Award winning singer-songwriter Mary Chapin Carpenter celebrates her thirty year recording career here by revisiting the cream of her illustrious back catalogue. “Sometimes Just The Sky” finds Carpenter reimagining one song from each of her twelve studio albums alongside the freshly minted title track, with uniformly compelling results. “The Moon and St.Christopher,” “Naked To The Eye ” and “Jericho” are the best of an excellent bunch.
