Bottom line:
Gianmarco, his music and band = AWESOME
It was too crowded, some people went to enjoy the show and the moment, not to record the whole concert. Having your hand up and your phone in hand blocks the view of the people in the back. Also I noticed that a drunk lady got up in the stage, Gianmarco didn't even moved and pretended that didn't happen, Please next time maybe making sure that the show is only for grown ups so everybody enjoys the show equally. Is like watching a horror movie at the theater, you want to quietly enjoy it but everybody does their best to keep you from doing it.
But Gianmarco was so great, that after all i believe it was an excellent show. He is a great artist and I hope he wins that Grammy.
