The Artist:
Edward Alexander MacDowell (December 18, 1860 - January 23, 1908) was an American composer and pianist of the Romantic period. He was best known for his second piano concerto and his piano suites Woodland Sketches, Sea Pieces, and New England Idylls. Woodland Sketches includes his most popular short piece, To a Wild Rose.
Info:
Written by Edward MacDowell in 1883 the 'Hexentanz' (Witches Dance) formed part of the '2 Fantasiestücke for Piano'. It's a very difficult piece, often used to showcase a pianist's skills. It seems to depict a tremendous whirling and swirling.
