I was at the Houston show and noticed all of coats pit members were wearing some sort of white devices clipped on their waist that connects to their ears through a headset. I'm not sure what those are, but some guy that sat next to me said it could be a click track (?)
Could someone explain why they would need a click track? Is it supposed to help them with tempo? If yes, isn't that kind of cheating? ;)
I will try to find a picture of their pit members so y'all can see what they look like
