Kara Walker is our Thursday Critical 21st Century Artist. She similarly needs little, if any, introduction, as she is one of the most celebrated contemporary artists today. Her work is powerful, provocative and an imperative if you don't already know it.
Per usual, an Art21 profile is available here (still) and here (moving) and on the shelf here at MLK at 709.2 W181.
