It is called "Danza de los Voladores" (dance of the flyers). Wikipedia says that "it is an ancient Mesoamerican ritual, which consists of dance and the climbing of a 30 meter pole from which four of
the five participants then launch themselves tied with ropes to descend
to the ground. The fifth remains on top of the pole, dancing and
playing a flute and drum. According to one myth, the ritual was created
to ask the gods to end a severe drought."
