As temperatures heat up around Chicago, so do the festivals throughout town. From the Chosen Few Music Fest to Summer Dance, Chicago hands-down has free (or cheap) fun and entertainment on the summer schedule. And one of the biggest festivals on the South Side is coming up—The Silver Room Block Party on July 21 from noon-10 p.m. In its 15thyear, the festival is sure to serve up the same fun and family reunion feel it has become known to provide.
