Like everyone else, I do dream of seeing my fave Bemani artists here in the US (specifically, LA). As for the American cities, here are the ones I immediately have in mind:
Seattle, Los Angeles, San Francisco, New York, Chicago, Dallas, Atlanta, Boston.
As for the acts, I am having a hard time... oh, what the heck. I just decided to split the songs by their solo and band gigs, as I group the artists (and by association and extension, vocalists)
either where they started their Bemani careers, have the most songs in, or the music game they are most likely associated with. Unfortunately, since my brain got fried from attempting to know ALL Bemani artists, this list turned out to be rushed.
And yes, I'll put a 5-song limit per act (like I said earlier, I'm separating them: solo/vocalist, band/group, collabs). So technically, some artists would perform more than 5, overall.
