“The Dirty Dutchess” is more than just a fundraiser, the evening will be a showcase of what’s to come: a night of live performances, behind-the-scenes demonstrations, and a glimpse into how the venue’s transformation is taking shape. There will be music (of course), but also theater and dance, a show that’s part concert, part immersive experience. Pop-up performances will take over unexpected corners of the theater, blurring the lines between audience and artist with burlesque performers, singers, dancers, and street performers of many stripes, including vocalist Andrea Burns, burlesque artist Qualms Galore, juggler Justin Weber, harmonica virtuoso Jiaya He, and hula hooper Pinkie Special. The evening will be hosted by actress Kaitlin Hopkins and Frank Castella Jr., president and CEO of the Dutchess County Regional Chamber of Commerce.
