For the first time in history skeletons will be dancing to a Mariachi band under the Kremlin walls on Friday afternoon.

Until 4 p.m. Una Probadita de México (A Taste of Mexico) is putting on a Day of the Dead celebration that starts at their headquarters in Gostiny Dvor and then dances in a procession up to the square. Although the holiday is usually celebrated on Nov. 1 and 2 — All Saints Day in western Christian churches — the Mexican fans decided to mark one of their most famous national festivities early.

In addition to fans dressed as extravagantly made-up and costumed dead people, there are bands, national dances, gigantic scary art objects and traditional sweets shaped like skulls.

At the end of the day the party will head off the square and back to Gostiny Dvor for more dancing and partying.
