Wes Roj says he was recruited by his friend and fellow Hawken School alumni Sebastian Orr to direct Orr’s Hum after it was accepted into Cleveland Public Theatre’s Big [BOX] series. The play tells four seemingly disparate stories that have common circumstances — all of which are tied together by the end of the piece. The stories are based on memories of four characters who have died: a young man meeting his ex-girlfriend, a young woman who loses her job and takes a road trip, a professor who uses math and philosophy to figure out why she lost her son, and David, “who tells the story of a nighttime visitor who made things clear to him at the end of his life,” says Roj. Hum plays at 7:30 p.m. tonight and tomorrow and at 3 p.m. Sunday at Cleveland Public Theatre (6415 Detroit Ave., 216.631.2727). Tickets: $12-$15. — Michael Gill
