T-shirt with leds blinking to music

Hello everyone,

I saw a topic (http://community.littlebirdelectronics.com/t/led-strip-lighting-with-music/20)

And I would like to do quite the same. My plan is to make a T-shirt containing strip leds and that will blink thanks to the music. We’re planning to dance on a wedding party.
I see two choices:
The first is to put the strip leds and the mike in the tshirt. The risk here is if the mike get noises and blink for nothing :expressionless:
As we’re going to be a lot of dancers, is there any possibility that everyone has the tshirt connected to a central Arduino or Raspberry ? And when we put the music on the player, it will start blinking the strip led on the shirts ? Obviously synchronously with everyone.

Do you have any idea on how to do that ? Without putting any risk and danger (skin burn …)

Thanks a lot !
