Thousand-Year Rainbow
I found a copy of alan's concert video the other day and watched part of it. (I accidentally downloaded a TV broadcast version first, which was only half of the concert. It didn't have "青藏高原" and Yesasia said it was supposed to be 2 hours long, so I knew there was something wrong.) In the concert, alan sang "千年の虹" ("Thousand-Year Rainbow"), which she recorded with Rin', a Japanese group that combines Japanese instruments with pop music. I found a a download for it today. You can buy the album on Yesasia, but it's expensive (because it's Japanese). You can see a Chinese translation of this song here, but I'm not going to verify it's accuracy, since I don't know Japanese. You can download the song here.
I also found out that there's an orchestra version of "明日への讃歌" ("Hymn for Tomorrow"), but it's on the Japanese single for the first "Red Cliff" song. I already have two CDs with different versions of this song on it, so I don't want to buy another one! XD I uploaded the version with the vocals here. The entire arrangement is very different from the original:
I don't have an MP3 for this song, but it's "天涯" ("Horizon") in Tibetan:
