Dance away your cares as Dance Caliente presents a free class on Lindy/Swing and Tango Line Dancing in Bonsignore Hall at the Charlotte & William Bloomberg Medford Public Library. Dancers of all ages are invited. Please RSVP through the library’s online calendar. Founded in 1998 by Eileen Herman-Haase and Raul Nieves, Dance Caliente brings a contagious enthusiasm to their instruction of ballroom and Latin dance forms. Other Dance Caliente classes at the library this fall will be on Lindy Hop/Swing Fusion (October 30) and Argentine Tango (November 20).
