About playing in different places

You can be 100% sure that there are going to be a pretty big number of questions in the words of "Can DT come and play here... etc etc etc"?

So, to kinda make it general and answer all those questions in one. "What are the minimum requirements and things to do to have DT playing in some venue or country?"

I know some, but I need to know the entire info to really make an effort on the right direction.

PEACE...
