The first concert happened on October 10th in Tokyo. According to Mahito Yokota (Super Mario Galaxy composer) via the official site, there were 150 musicians (100 instrumentalists and 50 voices) performing the music of the series. So far I was unable to find anything regarding the program, specific arrangement credits and any kind of bootleg recording (even though it’s harder to find these in Japanese concerts). What we know is that "Gerudo Valley" and a medley of boss battle themes is in the program (via official site), and according to pictures of the score released in the official Facebook page, the final battle theme against Ganondorf ("Ganondorf Battle") from Wind Waker, is also present. Also, according to the Official Nintendo Magazine, next year concerts will feature a four movement symphony, but only two of these will performed these year. This was expected, since producer Jason Michael Paul has already confirmed the presence of a 18 minute movement dedicated to Twilight Princess (it is apparently the second movement). It is also very likely that composer Koji Kondo was in attendance.
If anyone finds anything else, please share!
