Spanish composer Manuel De Falla composed El Amor Brujo [Love, the Magician; The Bewitched Love] between 1914-1915. Danza Ritual del Fuego, or Ritual Fire Dance, and the three songs for mezzo-soprano are the most-well known of these restored pieces.
English composer Gustav Holst composed The Planets between 1914 and 1916. The Birmingham premiere of the suite took place in 1918, fifteen years before Pluto was discovered. Though the Planets became by far the most popular work of Holst's and one of the most known pieces by an English-born composer, Holst did not consider the piece one of his finest. Partially because of this he never wrote an eighth movement, though unexpectedly the IAU relegated Pluto to the status of dwarf planet in 2006.
