A House With No Walls

George Washington’s slaves lived next to his Philadelphia presidential residence. The discovery of the shack’s remnants ignites a feud between a fiery black activist and a conservative black commentator, intimidating whites in this provocative little production. Who interprets history? And is an apology overdue? Or should we all move on? Th, F, Sa 8pm; Su 2pm. Through 5/29. $8-$15. Celebration Arts, 4469 D St.; (916) 455-2787; www.celebrationarts.net.
