A piece of music
from Edvard Grieg
's Lyric Suite
. Like the March of the Bumblebee
Somewhat similar in tone to In The Hall of the Mountain King, a fact not exactly suprising when one considers that the Mountain King in question was the king of the Trolls... Grieg based a lot of his work on Scandinavian mythology.
One of those pieces of music that is sadly underrated, and should be better known, IMO.
