Nice idea.
~~REVIEW~~
Wow this was cool, something new not alot of people would think of this, you did a good job with the effects, but im thinking it could use more, maybe add a "WILD" fan jumping around, or even some backround screen, but besides all that it was great i think you should add to this.
~~THINGS TO IMPROVE ON~~
Add more actions like the wild fan or backround big screen.
~~OVERALL~~
Design a concert, nice idea.
