Attending a silent disco should be on everyone's summer bucket list, and today is your chance to check it off. Grab your friends and head down to Playhouse Square this evening to dance about in silence while wearing wireless headphones. Tonight's theme: Old School Mixtape. Admission is free, but you'll need to have an ID to receive a pair of headphones. The disco takes place from 9 to midnight on U.S. Bank Plaza. (Niesel)
