The adopted child’s search for his birth parents or parent is often charged with risk. When writer-performer Michael Fosberg set out, in defiance of his biological mother’s wishes, to find his natural father, the Waukegan-raised pilgrim eventually discovered his roots in a proud old family. But his regrets at having been deprived of this rich, vibrant heritage are tempered by the awareness that he was also sheltered from an intolerant society. Following a successful run at Bailiwick Repertory, Incognito has moved to the Apple Tree Theatre. In this one-man show (again directed by Michael E. Myers), Fosberg acquaints us with the people he encountered on his odyssey, replicating their voices and mannerisms, while sharing with us his astonishment at his newfound identity and forcing us to question–as he does–its validity. “Did you guess when you first saw me?” he asks. “Did you see me differently after you knew?” Apple Tree Theatre, 595 Elm Pl., Highland Park, 847-432-4335. Through March 17: Wednesdays, 7:30 PM; Fridays, 8 PM; Saturdays, 5 and 8:30 PM; Sundays, 3 and 7 PM; Wednesday, March 13, 3 and 7:30 PM. $30-$35.
