Gustav Holst (1874 - 1934) is recognized today as the composer of "The Planets," which remains wildly popular, but for little else except perhaps his "St. Paul Suite." However, Holst was the creator of operas, chamber, vocal, and orchestral music of many different styles, based on subjects as varied as folk songs, Tudor music, Sanskrit literature, astrology, and contemporary poetry.
