In what's usually a sign of very, very poor ticket sales, the Turner Hall Ballroom announced today that Wednesday night's Gang Gang Dance/Marnie Stern concert is now free. Though the co-headliners each had breakthrough years, earning cheers from most of the important Internet music sites, including Pitchfork, neither yet has the name recognition (or in Marnie Stern's case, the mass appeal) to fill a venue the size of Turner Hall in a market the size of Milwaukee.
