Ali Gharavi is an Iranian writer driven from his native country during the 1979 revolution. The short stories that have anchored his work and the revolution that has fueled them have inspired Gharavi’s first play — Spring of Freedom, Summer of Fear — a nonlinear navigation through one family’s experiences. 3-Minute Egg dropped into a rehearsal and met with the playwright. The play, produced through Tablesalt Productions, opens Thursday and runs through April 3 at the Lowry Lab in St. Paul.
