So, last summer I participated in a recording session for a video game. It was VERY interesting, and now that the game is out I'm actually allowed to talk about it! It's called Ace Combat 3DS Assault Horizon Legacy, and you can see a preview here (and also hear me singing in the background! We were singing words, really.)
I hope I get to do something like that again; the people in charge of the recording session seemed happy with the work of the assembled singers, so you never know!
