The footage originally comes from the anime, "Neon Genesis Evangelion," or more specifically, from a recent-ish retelling of the original 26-episode show via a three-part movie series:
Evangelion: 1.0 You Are (Not) Alone

The music is clipped and modified from a track called "Highlander (The One)" as performed by "Lost Horizon," and mimics the style of the video below by repeating a video clip to the provided audio, in a growing meme perhaps best called a "face melter."
"WOAH-OH-OH-AH-AH-AH-AAAA-HA-AH-AH-AH Widescreen"

The audio recorded for this video was done with Audacity's record function as the WOAH version above played, and modified with fade-in and fade-out to sharpen the ends, and adjusted with Audio Speed Changer Pro to tempo scale -20%, pitch shift +4.0 semitones and a playback rate-adjustment of -20%. The video comes from a fan-produced, fan-subtitled version of the 1.0 film released by Kili-No-Fansub and clipped to avoid the appearance of any text (otherwise I'd've used more).

The publication of this video, which is not for sale or rent nor earns the editor no advertising revenue, is fair-use of copyrighted material, held by publishers for NGE and Lost Horizon but modified in a way that alters the original publication so as to substantially represent a new creation of which I hold no ownership claim to other than merely to have been the original editor.
All of the original audio is removed and replaced by the modified music you hear, but it still sounds like the explosions are still included somehow :-3
