Erykah Badu

Erykah Badu's influence on contemporary R&B can't be understated. She's served as the muse for rappers from Andre 3000 to Common, and her albums—including Baduizm and Mama's Gun—helped define the neo-soul movement. In recent year, she's gotten wonderfully weird and political, beating D'Angelo and Kendrick to the punch with righteous funk albums. This is as good as a Taste of Chicago gig gets.
