Akihabara (Otaku Mecca), are coming to the big apple. Created by songwriter Yasushi Akimoto, the group is supposed to exemplify "idols you can visit," or in this case, idols that visit you. Joining the trip with unrelated concert at Webster's Hall after the convention, the crew will be performing the normal role of a musical guest, with a Q&A, various autograph sessions, and a con concert.
Now, if you want commentary on their music, you'll have to ask someone else. I'm no Zac Bentz, and am actually the second to last person you should ask about Japanese pop music, so my unexcited review is probably not worth much. However, It is of note that Anime Vice will be at New York Anime Festival, so there's a chance that Gia will try getting some alone time with one of the 48 idols... for an interview, or something.
