Attending a silent disco should be on everyone's summer bucket list, and today — National Dance Day — 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. You can choose from three different channels that will be playing music from the '70s, '80s or '90s. Because it's a "silent" disco, you can turn up the volume as high as you want! 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)
