The European concert industry after the Paris shootings?

How the Paris incident is going to affect the status of the concert industry in local and global level? Several concerts that were scheduled for France are cancelled.

This means that the local promoters are going to lose money. Moreover, the US bands have to change their tour and add more dates in other countries so as to break even financially . The security of the concert venues have to be revised, probably the promoters have to spend more money on hiring more security staff or special devices for the gun control at the entrance of the venue. The local festivals in France (e.g. Hellfest) are going to lose money due to the reduction of the online ticket sales , since people fear about their security in concerts. The currency of Euro will go down on financial level and the US bands that have agreed on getting paid in Euros for the European Tours, are going to lose money as well. This fact may affect the production cost, so the US bands may play in Europe with a smaller stage show. I guess that the threats against new attacks in London and Rome, are going to affect the concert industry there as well…
