Revelers in the Ecuadorean village of Pillaro are ringing in the new year with a unique Latin American tradition: Dancing through the streets wearing giant devil masks with protruding horns and angry grimaces.

Nearly a week of festivities concluded Saturday as locals paraded in costume to the sound of trumpets and saxophones. Some spend hundreds of dollars on intricately painted masks.

There are diverging stories on how the tradition began. Similar celebrations are held in countries including Mexico, Peru and Bolivia.

Organizer Maria Alvarez says that in Ecuador it likely started nearly a century ago when young men from outside villages vying for girls' attention dressed as devils to hide their identity from angry relatives.

The festivities are said to grant blessings for the new year.
