The owners of the massive East Williamsburg music complex Avant Gardner — which includes the currently closed Brooklyn Mirage, one of the largest concert venues in New York City — have filed for bankruptcy.In a statement on social media, Avant Gardner said its Great Hall and Kings Hall event venues would remain open during the Chapter 11 process.
