As officially stated, the Russian shows got cancelled due to a heavy
breach of contract. The local promoter didn’t stick to any agreements.
The band made huge compromises to make the shows still happen. But they
got violated as well, again and again. There was no chance to find a
reliable base to make the show happen. The boys are OK, but they feel
extremely sorry for their fans, they are pretty down at the moment.The band is now looking forward to play a
great show Lodz!
