Isaiah is on stage now and just did the first run of the song. Until the visuals start on the led-screen behind the stage, there is actually no atmosphere in the hall at all as it's completely dark. Another thing that can't be noticed from the visuals the way it will be shown on tv is that almost during the entire song there is one or more images of him on those led-screen, which is really too much for me. It's distracting for who's in the hall and might get people to focus on the wall instead of on the singer on stage, but then, could that be what they want?
Other than that, Isaiah sounds fine and I don't notice major changes from the first rehearsal.
Still a pyro curtain and fountains during the last chorus on the still run. From the hall it looks redundant, but I can imagine on screen it might just be a nice extra touch..
