In 2008, Cai Guo-Qiang was awarded the 7th Hiroshima Art Prize, and was honored with a solo exhibition at the Hiroshima City Museum of Contemporary Art. A black fireworks performance opened the event.
I also liked his Black Rainbow explosion project for Edinburgh
I found the shape and color of each explosion matched the sounds perfectly. The rapidity and precision of the explosions and their placement in the sky was just stunning, resulting in a very pwerful experience. I would have loved to see this performance in person.
