What is "boombal"

Boombal (pl. Boombals) is a relatively recent phenomenon of folk dance parties in Belgium, originating in the French bal folk. The partygoers indulge in pair, ring, line, and string dances such as the waltz, polka, An Dro, etc. adapted from the French bal folk scene. The events are seen as a more social and enjoyable alternative to the individualistic dancing that is often seen in modern clubs. There is a very low barrier of entrance due to the emphasis on having fun rather than meticulously performed and complicated dances.
