Mad world In Yasmina Reza's darkly comic God of Carnage, two sets of well-to-do parents meet for a discussion after the child of one has knocked out the teeth of the other's child with a stick while playing in a city park. As the quartet of professionals — lawyer, money manager, businessman, and writer — try to talk the situation over, the discourse slowly devolves from civility to animosity to childish chaos. The show goes on at 2 and 7 p.m. Sunday at the Walnut Street Theatre, 825 Walnut St., and continues with shows at 8 p.m. Tuesday through Friday, 2 and 8 p.m. Saturday, and 2 and 7 p.m. next Sunday.

Material girl Puccini's Manon Lescaut was the great composer's first success, an overheated tale of a beautiful young woman pursued by two men, one offering love and the other riches. It all ends tragically, of course, with exile, death, and the searing aria "Sola, perduta, abbandonata" — which means, of course, it's opera at its finest. The Opera Company of Philadelphia performs the work at the Academy of Music, Broad and Locust Streets, at 2:30 p.m. Sunday, 7:30 p.m. Wednesday, 8 p.m. Friday, and 2:30 p.m. Sunday. Tickets are $10-$225. Call 215-893-1018.

The scientist From his tiny specialty, myrmecology (the study of ants), biologist E.O.

New roots The alt-Americana trio known as the Lumineers brings a rockabilly urgency to its hootenanny sound. The lyrically great tracks "Ho Hey" ("I don't know where I belong / I don't know where I went wrong / but I can write a song") and "Flowers in Your Hair" ("It's a long road to wisdom / but it's a short one to being ignored") off their sensational eponymous CD have jumped right to the top of our playlist.

Cruel to be kind On its surface, Steven Shainberg's 2002 film Secretary may appear to be a kinky satire of romantic comedies, but the story of an insecure clerical worker willingly dominated by her rigid, demanding boss ends up being a strangely affecting portrait of misfits connecting and healing.
