Her friends and family may call her Chan Marshall, but the music-loving world knows her better as singer-songwriter (and actor and model) Cat Power. I first encountered Power opening for Liz Phair in the mid-'90s, then crushed on her 2003 album You Are Free. I even followed her excursion into Memphis soul, starting with a wonderful album of original material, The Greatest. Then, it seems, touring and booze got the better of her, and stories of bizarre concert behavior started dogging her career. It seemed for a while she was destined to burn out and fade away. As luck would have it, though, Power was able to kick that bottle. As a result, perhaps, her fascination with Delta blues gave way to more personal, vital, even humorous material on Sun, her latest collection. It'd be hard to imagine a more bracing anthem, for example, than "Human Being," which insists, "You got a right to scream when they don't want you to speak." Well, get ready to scream, Oly Sun-worshipers! Cat Power has returned from the blues.
