I love this. A lot. Mesmerising. This piece by Enra is called pleiades.

Enra is a Japanese troupe that combine dance, performance art, music, technology, light, music and more to create, in this case, “magic.” Incidentally, pleiades  “is an open star cluster containing middle-aged hot B-type stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky.” (Source: Wikipedia)

The people behind this dance/light performance are:

Music and Direction – Nobuyuki Hanabusa. He is also enra’s team supervisor.

Choreographers and Dancers – Saya Watatani and Maki Yokoyama

Animation – Seiya Ishii and Nobuyuki Hanabusa

This is Enra.
