If the conflicted conscience that keeps you up at night had an inner voice other than yours, it would be Aimee Mann. The Oscar-nominated, Grammy-winning artist has a knack for mixing sweet and sour. The milk-smooth voice of empathy and the sharp barbed lyrics of critique. You can hear it in her integral soundtrack to Magnolia, featuring Save Me and Wise Up, as well as in her poppier songs, like That’s Just What You AreCharmer, and her ‘Til Tuesday hit, Voices Carry. She’s played a nihilist in The Big Lebowski, herself in Portlandia, and now the Main Stage in Pleasantville.
