Saturday, 8 p.m.

World Cafe Live, 3025 Walnut St.; $10, 215-222-1400;

This North Carolina folk band may be named for a minor character in the “Lord of the Rings,” but if they indulge any fantasy it’s closer to troubadours at a Depression-era country fair than travelers in Tolkein’s Middle-earth. Their stomping, upbeat music often belies dark, lyrical content about freaks and misfits. Fans of Neutral Milk Hotel and the Decemberists will dig them.


Osvaldo Romberg: Dirty Geometry

Through May 30

Pentimenti Gallery

145 N. 2nd St.

Free, 215-625-9990

This is the first solo show in Philadelphia for Argentine artist Osvaldo Romberg, who contributes paintings, sculpture and works on paper. “Dirty” here isn’t a sexual innuendo but rather refers to Romberg’s ambition to, in his words, “invent a geometry that would be free from theory.” This involves intentional imperfections, personalizing a rarified mathematical universe.

It’s part of the Philadelphia Science Festival.

Kimber Lee’s play looks in on the life of Tray, a Brooklyn kid who’s trying to figure himself out amidst the demands of others —  he’s got all the people in his life asking for something different, but who is he to himself? And what if he has less time than he thinks to sort it out?
