Leaving the show by Ney Matogrosso and extremely disappointed.
I've never been to a show with such a bad sound.
The boxes seemed to burst and compromised and very much the whole presentation ...
I made a complaint with the responsible and she informed that the problem would be of the production of the show ...
Nothing was done.
