The folk songs and dances of Russia have been preserved through the efforts of the Pyatnitsky Choir (officially known as Pyatnitsky State Academic Russian Folk Choir). While they perform a mixture of traditional tunes and modern compositions, they are best known for their interpretations of songs that go back as far as the 18th and 19th centuries. Many of these tunes were collected by members of the choir during field expeditions in Russia's rural areas. The choir, which recorded more than 400 cylinders of folk songs for the Gramophone Company in 1911, continues to perform around the globe. As of 2000, the choir had appeared in 40 countries. According to West German newspaper, Dortmunder Tageszeitung, "Today, the choir's performances are a synthesis of song, music, and dance, with the concertgoer being hard put distinguishing between dancers and singers."
