BARBECUE by Robert O’Hara (“The Inheritance,” “Slave Play”) debuted at The Public in 2015, and is now presented as a streamed reading with Laurie Metcalf, Heather Simms, David Morse and more. The O’Mallery family assembles for a festive outdoor gathering. While awaiting the arrival of their youngest sister, Barbara, members of the family express their concerns for her well-being. Family secrets are uncovered, their perspectives are questioned, and what appears to be a friendly and casual reunion reveals itself to be something else entirely.
