Sometimes, you just gotta have faith. That's what Starving Artist Productions — the theater group behind The Birth — is doing while staging playwright Brian Friel's Faith Healer. Three characters reflect on the 20 years they've spent together traveling the countryside of Scotland and Wales: Frank a faith healer, Grace his mistress/wife and Teddy the booking agent. Play contains mature themes and some strong language. $20-$22. May 11-12, 7:30 p.m.; May 13, 8 p.m. Duke Energy Theatre, 345 N. College St. 704-372-1000. www.blumenthalcenter.org.
