The House of Dang party Friday night is sure to be a blowout. Owners Doug Voisin and Andrew Bayer are closing the store and moving to Oak Cliff to focus on their clothing line. So everything in the store is on sale. Besides that, their dance party Friday promises trashcan punch (no, thanks) and wine boxes (yeah, still no). But you can bring your own libations and enjoy the deep discounts and music. Plus, And/Or Gallery, which also is closing, is throwing a 90s-style rave next door.
