Dancing - Esplanade de la BNF

There are always groups of dancers on the esplanade of the Bibliothèque nationale de France (François Mitterrand site). The wooded floors are a bit springy and they use the reflections in the windows as mirrors. I'm no expert, but it looks like they mostly do hip-hop and k-pop. My photo doesn't capture much, but these two were really good and clearly having fun.
