Well, on the subject of big-name performers, Modest Mouse is set to take the stage at the College Street Music Hall exactly one month from today. But, for the moment, we’re more interested in the “Float for Peace” dance party taking place this evening at 6 p.m. Starting at the Women’s Table, the event invites attendees to dance to music playing in their own headphones for 90 minutes in what’s meant to be just one of several “silent discos” taking place around the globe at the same time.
