Finlandia, Op. 26

Jean Sibelius (8 December 1865 – 20 September 1957), was a Finnish composer and violinist of the late Romantic and early-modern periods. He is widely recognized as his country's greatest composer and, through his music, is often credited with having helped Finland to develop a national identity during its struggle for independence from Russia.  [source from Wikipedia]

This symphonic poem composed by the Finnish composer Sibelius takes about seven minutes. In 1899, Sibelius completed the first version as the incidental music of the patriotic drama "The Scene From Time Immemorial", and revised as the "Finlandia Hymn" later in 1900.
