Hopefully you already know this but, concert lasers will kill your camera. They are bad for your eyes and equally so for your lovely camera sensor. This isn't a random unlikely occurrence. It will happen every time, to any camera with a digital sensor. It doesn't even matter how high-quality your gear is as evidenced by the above video from a once lovely RED Epic. Apparently the video was taken during the Electric Daisy Carnival 2013 in Chicago and is from one of the two cameras destroyed that day.
Of course the cameras can be repaired for less than what they cost but it's still damage that renders it useless until repaired.
In summary, today's lesson is that in the game of Rock, Sensor, Laser... I'm playing laser every time.

UPDATE: Apparently the cameraman has removed the original video and another link to the original hasn't surfaced yet. However, I've found another example of the same situation and updated the video. All I can show you from the original are these two before/after screen grabs.
The alternate video now shown at the top of this article is from an unknown music festival last year shot by MLC Productions. Yes, that means this has happened more than once.
