Some performers work hard to let you know they're working hard for you. Not Norah Jones. She's the kind of artist who works hard to make it all look easy. Jones' first set of all self-written material keeps the same languorous, casual sunny morning feel of her first two albums, but there are some marked differences this time out. Jones' material now contains a new bite, as the effects of fame, old betrayals and (most importantly) her country at war have all crept into her work.
