If you've been following my posts for any given period of time, you'll have read my post on civilians in the UNSC. Particularly, the apparent lack of changes in culture, fashion, et al. This blog is dedicated to one thing: music. Music has been a part of human culture since the Neolithic Era at least, possibly longer. It's a huge part of Western culture and youth culture in the First World. So where is it in Halo? I don't mean the Marty O'Donnel stuff, the orchestral pieces and the soundtracks. I mean civilian music. Pop, rock, metal, rap, punk, where is it?
So far, we've heard only a few instances of civilian music in the 26th Century. We've heard thumping dance music in Club Errera (Halo: Reach), and of course, Never Surrender. As an aside, Never Surrender is likely just an easter egg by Bungie. It's doubtful that the denizens of Reach play that in clubs. As I said in my previous post, civilians really don't play a huge part in Halo, so as to focus on the military story of the Human-Covenant War. But you'd think that in Halo: Reach, a game that features civilians far more than previous games, would also feature more music.
What do the people of humanity listen to? We know that a form of metal is fairly popular, I forget the name. It is certainly very similar to 21st-Century heavy metal. Some form of dance or dubstep is likely popular, given its presence in Club Errera. Beyond that, very little is known. Older music, such as the metal that SgtMaj. Johnson listens to, has a similar status to today's "classical" music (Beethoven, Bach, Tchaikovsky, etc.). Few people seem to listen to it, though; a Marine comments to Johnson to "turn off that old stuff", suggesting that it really isn't popular or well-liked.
Just like the rest of the civilian world, music is apparently not very well explained in the Halo expanded-universe. But, we can all at least breathe some sigh of relief; rock hasn't quite died yet.
