Kanye West has performed so many times, he knows the protocol, and he's become nothing short of a perfectionist. That goes for his music, his videos, and even the lights that are supposed to be flashing during his perfomance of "All Of The Lights."
During this concert in Washington D.C., he had to cut the song short twice and call out the lighting guy for not turning on all of the lights during the performance. He finally got it right on the third attempt, but he was 30 seconds away from this Yeezy moment escalating.
After things were straight, Kanye went on to kill his performance.
