Sibelius (1865-1957) was a Finnish composer, generally regarded as one of the greatest symphonists. It is remarkable though that many classical music lovers rarely venture beyond the seven symphonies, the violin concerto and occasional pieces like Finlandia and Valse triste. I have selected what I consider his best work, his final completed composition, Tapiola, Op. 112, from 1926, one of the greatest symphonic poems of all time. Relevant links below.
