I wonder why they preferred to pre-record it. They broadcasted concerts live when she was tired, vocals not that great and of course live audience but in a more controlled setup they prefer to pre-record everything.
I don't mind, cause you still get the live feeling since I agree that her voice doesn't seem to be tempered with, it's just interesting how times are changing and the online era will start to dominate with perfectly arranged concerts and visuals.
I also thought that the editing during SIGNAL is actually possible during a live broadcast, but maybe it wasn't the case here.
Anyway, it was really an amazing show full of emotions
Glad I bought the ticket.
