Battle for Umbara

I honestly have no idea where this piece of music comes from. I searched and searched, but couldn't find out who originally made it.

I really like how it starts out softly with just the piano, and then adds new instruments one after another, until we've got a really good [insert technical music term] going on. Plus, the Battle of Umbara automatically makes everything better. Kinda like Bacon. So yeah.

Oh, just a note: the music stops about halfway, and you get to hear Rex, Fives, Tup, and the rest of te 501st legion yell at each other while fighting off an Umbaran militia ambush. Fun stuff! The music starts over a few minutes late, and we get to watch General Krell steam-rolling the 501st and 2012th. Not so fun. :P
