Pennsylvania Playhouse has delivered an enjoyably intimate and gripping production of the Pulitzer Prize winning play "Proof."

The haunting and satisfying show is at Pennsylvania Playhouse, 390 Illicks Mill Road, Bethlehem through Feb. 11.

"Proof" tells the story of Catherine, the daughter of a recently deceased mathematical genius, and her struggle with mathematical genius and mental illness.

Northamptom Community College Theatres premiere of "Collective Rage: A Play in Five Betties" is jolting, raw and hilariously funny. The play in Norman Roberts Lab Theater at the Bethlehem Township campus through Jan. 22, is a raucous roller-coaster ride through the lives of five very different New York City women, coincidentally all named Betty.

At first all seem stereotypes, but as they come together to create a piece of devised theater, they find themselves rejecting the roles into which they have been cast.

Audiences are taken on a wild, irreverent ride with "The Many Charms of Symon Tuttle (A Strange Christmas Play)," which runs through Dec. 23 at The Charles A. Brown Ice House in Bethlehem.

"The Many Charms of Symon Tuttle" is a new play written by written by local playwright Bruce Brown. It is a crazy, farcical murder mystery which takes place right before Christmas.

The show sets the stage before it even starts with slightly-off sounding minor key versions of Christmas carols, followed by videos of humorously over-indulgent holiday decorations.

As the lights go up on the multi-color tree-bedecked set, the possibly drunken Symon Tuttle, played with giddy abandon by Jake Walbert is singing a slowed-down carol when a shot rings out.

Playful and spontaneous, Sing for Americas "The Wizard of Oz" through Dec. 17 at The Confluence Community Center, 610 W. Berwick St., Easton, constantly surprises.

Full of dancing, eye-catching costumes and unexpected visuals, Sing for America puts their own twist on the familiar tale of Dorothy and her friends in the land of Oz.

Leianna Torres is sweet and spirited as Dorothy, the young girl who is transported by a tornado to Oz.
