Now I'm back to Japan for vacation. I went to the concert of ASKA, which is the main feature of this stay in Japan. http://scene.chage-aska.net/
(His latest song "UNI-VERSE" is really impressive song at the first listening.)
There is one element in the concert that might be the first time in the history. That is ths style that he sings with orchestra not with band. Besides, he changes it city by city; for example he sings with Tokyo City Phillharmonic Orchestra in Tokyo while singing with Central Aichi Symphony Orchestra in Nagoya.
Also there are 3 cities included from foreign countries, Singapore, Bangkok and Shanghai and he began this tour from abroad.
There might be a concert with orchestra for special one-time only in the past. However ASKA is the first musician who did concert tour with orchestra and even went to foreign countries, too.
