question: In what country did Rakoto Frah's troupe win the gold medal?
context: Rakoto's opportunity for national fame arrived with the 1958 visit of French President Charles de Gaulle to Madagascar. The visit was in conjunction with the dissolution of colonial status and naming of Philibert Tsiranana as Prime Minister, part of the island's transition to full independence in 1960. Tsiranana had previously seen the flutist perform and invited Rakoto and his group of 18 musicians to accompany de Gaulle and perform traditional pieces during a portion of the French statesman's walking tour through the capital city of Antananarivo. Following this performance, Rakoto dedicated himself full-time to a career in music, performing regularly at traditional celebrations on the island. Tsiranana, who became president of Madagascar two years later, was the first to refer to the artist as Rakoto Frah, the name that the musician would use for the rest of his career.International recognition of Rakoto Frah and his performance of traditional sodina music began with his first overseas voyage to Algeria in 1967. The artist led a troupe of 18 Malagasy musicians selected to represent the island's various ethnic groups at the International Festival of Algiers. Among the 80 competitors hailing from a variety of countries, Rakoto Frah's troupe won the gold medal. This success was followed by performances in Japan, England, the United States, India, Germany, China, Norway, Finland, Australia and France, making him one of the first musicians to perform traditional Malagasy music at music festivals and concerts outside of Madagascar. At these performances, he was often accompanied by supporting musicians under the group name Orchestre Nationale. By exposing international audiences to sodina performances, Rakoto Frah promoted the instrument and the traditional musical heritage of Madagascar across the globe. The government of President Tsirananana fell into disfavor and was overturned in 1972, and Rakoto Frah's close association with the unpopular former head of state led the artist to be marginalized for the first half of the administration of his successor, Didier Ratsiraka (1975–1993).
