Причина - организатор JC Sound

Вот цитата с офф сайта:

Moscow show is cancelled

We are very sorry to announce that the Moscow show is cancelled.

The local promoter (JC-SOUND) was unable to fulfill every detail in our mutual Agreement for the show.

We can just hope that they will refund all the money for the people who had already bought the tickets for the show.
