Rachael Yamagata has become a 21st-century Emmylou Harris: a go-to gal for earthy harmonies. (Her sleepy soul has deepened albums by Bright Eyes and Ryan Adams.) But this double album pushes past familiar singer-songwriter fare into bolder regions: Elephants is a hushed mood piece that's all wet vowels and damaged love; Teeth is filled with rock & roll bite and gloves-off verses like "Don't fuck me in front of me" ("Don't"). Bright Eyes producer Mike Mogis delivers some of his lushest work ever on cuts like "Sunday Afternoon," helping Yamagata bring drama that smolders more than shouts, and is no less gripping for it.
