CROWNING ABBA'S RIGHTFUL HEIR: She's not as soundtrack-ready as Swedish countrywoman Robyn, but Lykke Li still knows how to give audiences what they want: Big, fat, pure pop songs with hooks that catch you from the first spin. Li takes the stage at the Highline Ballroom to show you how it's done. 9PM.
FEELING FEMINISTIC: Suzanne Braun Levine wrote an embrace-your-age ladyscreed called "50 is the New 50," and to promote it, she's invited along a few fiftysomething dames -- like Gloria Steinem and Isabella Rossellini -- who make the half-century mark look pretty fantastic (and not just because they're gorgeous). Barnes & Noble Lincoln Triangle, 6PM.
CHECKING IN WITH THE LOCALS: Pride-of-Brooklyn Paul Auster gets the interview treatment from Granta editors John Freeman and Alex Clark, and also reads some of his contributions to the lit rag. New School, 6:30PM.
