Task: Question Answering
Input (English): Passage: Philibert Rabezoza (1923 – 29 September 2001), better known by the name Rakoto Frah, was a flautist and composer of traditional music of the central highlands of Madagascar. Born in 1923 near the capital city of Antananarivo to a poor rural family, Rakoto Frah surmounted the challenges posed by his underprivileged origins to become the most acclaimed 20th century performer of the sodina flute, one of the oldest traditional instruments on the island. Through frequent international concerts and music festival performances, he promoted the music of the highlands of Madagascar and became one of the most famous Malagasy artists, both within Madagascar and on the world music scene.
After gaining regional recognition for his sodina skills as a youth, Rakoto Frah rose to national fame in 1958 when he was selected by Malagasy President Philibert Tsiranana to perform on the sodina for the visiting French president Charles de Gaulle. This event launched his career as a professional musician.  He first played at traditional ceremonies around the country, then expanded his performances from 1967 to include participation in international music competitions and festivals. His popularity declined in the 1970s but underwent a revival that began in the mid-1980s and continued until his death in 2001. During this period Rakoto Frah recorded ten albums, toured extensively in Madagascar and overseas, was featured in two French documentaries, and collaborated with a variety of international and Malagasy artists. Over the course of his career he recorded over 800 original compositions. Rakoto Frah and his sodina were depicted on the 200 ariary Malagasy banknote in honor of his key role in revitalizing and internationally popularizing the sodina. Despite the artist's worldwide acclaim, he lived simply and died having earned little from his lifetime of musicianship. His death was widely mourned and marked by a state funeral, and in 2011 a famadihana (the Malagasy highland "turning of the bones" funerary tradition) was organized to celebrate the artist's life. 
Question: What is the common name of the person who underwent a revival in the mid 1980s?
Output (English): Rakoto Frah.
