thank you for comments!
This is a presentation at RWB School Professional Division. They do not decorate the classroom, only the black floor and black drapery. At this time, they also set up a screen for a video presentation.
The first couple are RWB students and it was a dance from the Don Quixote ballet.
The second dance from Swan Lake from RWB itself.
For me personally, dancing without scenery allows people to concentrate more on the artist.
