Harana movie is currently in production. Here's the info found from the official website:
The Harana documentary film explores this custom and its music through the eyes of classical guitarist Florante Aguilar. Born and raised in the Philippines, as a young boy in the province of Cavite, Florante heard music and mythical stories spoken by his elders. Now living in the US and championing Filipino music - Florante travels back to the home country to search for and rediscover the last surviving practitioners of a long lost art - before its complete demise.
Led by award winning director Benito Bautista, the film contains a treasure trove of beautiful Filipino music awaiting to be rediscovered. Intent on preserving vanishing customs, the film rekindles a connection with the past before it is irrevocably lost, and portrays a side of the Philippines rarely seen.
