As officially stated, the Russian shows got cancelled due to a heavy breach of contract.
It was due to the local promoter not adhering to agreements.
The band made as many compromises as they were able, but they were screwed over repeatedly.
Tom, Bill, Gustav and Georg are okay, but extremely sad and hurt for the fans.
They are looking forward to performing in Lodz.
