Where did Ayu's performing style change?

[alternarist]

in AT 2007, ayu made the most eye contact with the audience. with 5 songs for audience participation, evolution, UNITE!, SURREAL, AUDIENCE and Boys & Girls, ayu truly showed that she want to get closer to her fans!

Well, i guess for the example of appears.. it's a different way of performing. She chooses how she wants to perform one song. Another example would be A Song for XX. In A Museum she literally stands there and sing but for BEST of CDL 0607, she had the whole martial arts going on..

So i guess it's just a matter how she wants to perform and not about changing style imo.
