No, thay made a contract about guesting in Belgrade (capital of Serbia) in May, but they delayed that tour, due to "dangerous and unstabile situation there"

Maybe I would go to the concert in Belgrade, but now there is nothing I can do about it... However, I watched some of the spots from their concerts, and it looked like there was an indeed great atmoshpere

It is always nice to see, atmosphere and the way people feel and enjoy are the most important things on live concerts. Kiss seemes to do really great job when we are talking about that, and I respect them.
