Leo Renier is a former Roman Catholic priest and Belgian musician, living in the Philippines since 1969, responsible for the preservation of the Spanish Historical Organs in the Philippines and the revival of its organ culture. He is the moving spirit behind the performance of Baroque music in a country, which eventually may lead to the discovery of Philippine Baroque music. He is the founder of the Las Piñas Boys Choir (1969) and of the International Bamboo Organ Festival, held every year since 1976 at the St. Joseph’s Church of Las Piñas, Metro Manila, a former school director of St. Joseph's Academy until 1994.
