Good musical guests at anime cons this year.

So far we've got:
Yuki Kajiura at Anime Boston.
FAKE? at Anime Next (going to have to go to that now......)

Edit: I forgot about M.O.V.E. at Anime Central. That'd be pretty fun.

Looks like Anime Expo has Morning Musume- but it doesn't look like they have a concert scheduled? And ummm, I'm not sure if I'd want to put Morning Musume in with the same kind of 'good' as Yuki Kajiura and FAKE? truthfully.

So... Otakon, how 'bout them guests?
Perhaps... Abingdon Boys School? SKIN? (where the heck is that album they were going to make...) The Glorious U.S. Return of Yoko Kanno?
