Woops. I'm a month+ late to this thread, but I can answer the "from Boston" stuff.
Hitoshi Sakimoto was in Boston, and recorded Odin's Sphere and a bunch of other things there with us (Video Game Orchestra) The recording session itself for the Odin's Sphere segment was also streamed live, hence 'from Boston'
As to why it's a point worth mentioning on stream, maybe because we've done everything from God Eater and Tales of, to Kingdom Hearts and Final Fantasy lol.
Has nothing to do with the setting of the game(s) nor style of music.
