||Gustav Theodore Holst (1874-1934) was an English composer and was a music teacher for over 20 years. He is most famous for his orchestral suite in seven pieces called The Planets, completed in 1916 during the middle of World War I (ironically, the same year that the VI Summer Olympiad in Berlin was cancelled due to "The Great War"). The first of the seven pieces is "Mars", referred to by critics as the "most ferocious" and "most devastating" piece of music ever written, evoking a battle scene of immense proportion with its blatant dissonance and signature 5/4 meter (changing to 5/2 and 3/4 at its conclusion). Holst directed that it be played slightly faster than a regular march, giving it a mechanized and inhuman character. "Mars" is easily Holst's most famous piece, and has been quoted in everything from Carl Sagan's Cosmos to The Venture Bros. episode "Hate Floats".
