For the Halo fans (and any +Lindsey Stirling
fans who were unaware this was coming out today).
Having never played Halo, I have no idea how this arrangement compares to the actually in-game music (Halo fans, feel free to chime in with comparisons).
According to the behind-the-scenes video (linked to the medley video), the guys in the Halo suits flew in from all across the country to participate in this. That's pretty cool. #Halo #LindseyStirling
