So far I have only seen Rollin and Sparkle.
The biggest positive for me was that I liked the stage. The rest, not so much.
Ayu just looked weird a lot of the time with that outfit and the faces she was pulling throughout both performances.
I like the song Rollin' and the concert reports were right - it certainly does have weird choreography.

Her voice was not very good in this song.
Sparkle was basically how I suspected from the news clips - the only part that seems live is the ending no no nos especially when you compare to how her voice sounded just a few seconds earlier in Rollin. So I'm not the biggest fan of this performance either; but I never liked this song much to begin with anyways.
I know this is the part of the concert that most people were looking forward to the most, but for me this is probably what I want to see least, so hopefully the rest is better.
