Brandi Carlile lends her voice to "Last Tears" and it's like she's been singing with Amy and Emily for years. So does Pink -- that's her on "Rock and Roll Heaven's Gate." Those, "Penguin" and "Three County Highway" are my favs but the whole album is an easy listen all-the-way-through. The critics loved it as much as fans -- some calling it their strongest so far at the time.
