I believe they did do the field music from Twilight Princess, yes.
Looking back on it, that was kind of a lame recap, but that's what happens when I leave it for a few days later and then try and write it late at night when I'm exhausted. Also, typing on an iPad is something I'm still not used to.
But yes, I should have said more about the music itself. Though it's not easy to describe in mere words what must be heard. The host even made direct reference to the orchestral CD that comes with Skyward Sword, but said that it's another thng to hear symphonic music live, and he was right. When I played Twilight Princess, my eyes got all watery when the original Zelda theme played during the credits. And that was just the music from the game, so I may have gotten a little teary-eyed during the concert itself.
The arrangements are beautiful medleys, flowing from one track to the next. The video footage matched well (just as you would expect, like at Video Games Live, but I still think it's impressive to match live-performed music to pre-recorded visuals). They do often cut to showing what the orchestra is doing, so there's a recognition of the people involved in the performance as well.
One thing that I almost have to roll my eyes at when at Video Games Live is when Tommy Tallarico goes on about proving that video games, especially video game music, is a legitimate and culturally significant art form, but I guess my "yeah, no kidding, let's move on already" attitude is because I already know it myself and being at multiple VGL concerts I feel he's beating a dead horse. I guess there does still exists a misconception that video game music is somehow different than non-video-game music, so I don't disagree. But The Legend Of Zelda: Symphony Of The Goddesses doesn't feel a need to beat that point over our heads, at least not by saying so, but rather by showing us so. I guess it helps that Zelda games are already beautiful visually (generally), but even if there were no visuals, I'm sure the music alone would make me want to replay those Zelda games. Even these days when I simply don't have time to keep up with the games I want to play, that playing games more than once is a rarity, I wanted to take on Twilight Princess again. Or even the whole series, sheesh.
It would almost seem rude to say that I would have liked to hear more of certain things. Since there was a dungeon music medley, a boss medley would also have been nice. They played a tiny bit of the A Link To The Past boss music, but I really like that tune so I wanted more. The Ballad Of The Wind Fish makes perfect sense, considering all the instruments involved, so I'm glad they played that (oddly without visuals) but the handheld games were otherwise grossly underrepresented. And considering they brought out a Wind Waker-like conductor's wand, they should have had a blue ocarina (and showed it off) when they played the ocarina songs medley and/or for the Ocarina Of Time segment. I guess even if they had to play those with flutes or other wind instruments instead, it still would have been a nice touch to show it somewhere, somehow, being the titular object in the series' most-known game. And lastly, the very rousing main The Legend Of Zelda theme was okay when they played it at the beginning, but for some reason I felt it was better performed at VGL, and it would have been nice to hear it played again (perhaps arranged slightly different) as a closing segment. I don't know if that might be asking too much, but it's one of the most well-known game themes, ever, and deserving of an encore itself.
But again, in short, it was probably the best concert I've ever been to, so hopefully it comes near you if you haven't been to it yet!
