The Planets
The Planets Op. 32 is a seven-movement orchestral musical suite by the British composer Gustav Holst, written between 1914 and 1916.  The first complete public performance happened during World War I on 10 October 1918 in Birmingham, with Appleby Matthews directing the orchestra.  However, an earlier premiere for only a small group of people was held on 29 September 1918 in the Queen's Hall in London, with the orchestra directed by Adrian Boult.  The seven pieces are all named after planets.
