I'm not sure how the person got the two wristbands to light up at different time and in different colors. My guess is that the sound is loud enough, and those particular wristbands sensitive enough, that it's the vibration of the song that's causing them to go off.
Fun fact: the wristbands can work at multiple concerts. My one from Detroit worked in both Cleveland and Pittsburgh. All three of mine should still work. I actually stuck the tab back in two of them before the end of my last concert to keep them in "listening" mode. I wanna see if I can hijack them should I decide to go to one of the Columbus dates lol.
she is such a legend
Every time it seems like she has a chance a new release swoops in and blocks her.
