I'm in love with these two songs right now:

Warframe - Multiple Bio-Signatures Detected (The entire song is great, but 0:43 to a little past a minute is the sweet spot)


And from the LOTR ROTK, Shelob's Lair (Should start at 0:55)


This kind of orchestral music, high intensity, crazy tempo and really outrageous sounds, it's so awesome, and I've just recently discovered it thanks to Warframe. I've no doubt that there are all kinds of songs like these, and I'm sure there are people who frequent MMO-Champ that know some, which is why I made this thread.

Post some similar orchestral high intensity, scary or direly epic songs here for everyone to enjoy! What's your favourite? What's the most memorable? I'm just now discovering these, so I'm very interested to see what you guys have to recommend.
