The concert is not bad but I'm worried about her ears' health. From November we could see and hear there is something wrong. She couldn't clearly hear herself and she didn't stop to focus to try to sing well while she was singing off-key 95% of the time. I don't count Moments and M because I don't believe that she can sing two songs (and one of her most difficult song of her discography) in a row almost perfectly while all the rest from November to B&G was mostly bad. They were surely lip-synced. During Next level she was slightly out of time with the instrumental at a moment.
I can understand why she burst into tears in Love song.
That's sad because I believe that she trained to sing so much in spite of her half-deafness (the beginning of cdl and the last TV lives proved it, she can control her voice) but loud music during concert killed all her efforts.
