Mitsuda and Millennial Fair are performing Brink of Time live in July. You can still get tickets!

Also, I'm going to go ahead and link to a
trailer I made for Xenoblade X. It's an amateurish patchwork of unrelated videos (all released prior to the Japanese release, so no spoilers), but it uses the theme Mitsuda wrote for Terra Battle.
Why, oh why, Takahashi. You could have had this for your main theme!
