This looks like a very cabal like festival. Some of the costumes remind me of Gotthard Tunnel ceremony.
They are also similar to the Krampus celebrations, or the weird carnivals i saw pictured in the UK last summer.
Very evil/pagan like style.
Swastikas, zombies and skeletons: Villagers dress up in bizarre costumes for ancient Macedonian festival marking beginning of their New Year
Thousands of revellers from across the world flock to Macedonia to celebrate 1,400-year-old Vevcani Carnival

Avant-garde costumes and make-up feature swastikas, pig's heads and skeletons in unique celebration
Macedonian revellers are flocking in their thousands to celebrate one of the longest-running, and strangest, carnivals in the world.
Featuring swastikas, zombies and skeletons, there is no shortage of pomp and pageantry at the Vevcani Carnival, which is believed to be 1,400 years old.
The pagan festival is held every year on the eve of the feast of Saint Basil (January 14), which also denotes the beginning of the New Year according to the Julian calendar, observed by the Macedonian Orthodox Church.
Combining pre-Christian customs with modern forms of expression, the Vevcani Carnival is said to 'transform the needs of contemporary society' by addressing topics of the day.
Named after the village of Vevčani, the Carnival officially became a part of the World Federation of Carnival Cities in 1993.
During the boisterous proceedings, traditional music is played on zurlas (a traditional double-reed woodwind instrument) and drums by Carnival participants known as 'Vasiličari'.
And carnival-goers lacking the necessary instruments still make their presence heard with bells, pots, pans, and even bins.
