I am the uploader of the video, its a section of the movie perico ripiao. I haven't had the honor to see palo' de muerto being played in person, but i have both heard recording and oral stories of it. It is not very easy to just randomly see this, as its only played during the burrial or wake of a person. It is usually attributed to a member of a cofrardia (society), the place where this is still SUPER common is Villa mella, and it can still be found all around the island in random countrysides. But your best chance of seeing one is going to villa mella, this inheritance is directly from the Kongo kingdom to D.R. Similar drummings dedicated to deceased members of a society are to be found in cuba by the practicioners of palo mayombe, the jamaican kumina which are of kongo extraction as well do a very similar drumming.
In D.R these are traditions that are dying out slowly because the young take no interest in keeping these traditions alive, specially when these kids assimilate into the big cities, and become reggaeton heads. :ninja:, Fortunately, these traditions are still being kept alive by the brave men and women all over the island, and abroad.
