Hungarian Rock by György Ligeti
Imagine if Bilbo and the dwarves were robots.
Off they go on their adventure! As robots they can’t feel the hardships of inclement weather or food shortages, so they’re basically happy and oblivious for the entire length of their journey.
(3:01) Suddenly, they find Smaug and things grind to a screeching halt…the dwarves now mourn the deaths of Thorin, Fili and Kili.
Despite their overwhelming loss, the music ends on a somewhat happy note. After all, the hobbit and dwarves did fulfill their quest…albeit at a steep cost.
