В общем вот официальное заявление Эвиденса:

OFFICIAL PRESS RELEASE: May 17, 2010

MOSCOW SHOW

Due to unforeseen circumstances beyond my control, the Evidence concert scheduled for May 27, 2010 has been cancelled. Despite any rumors to the contrary, technical and contractual issues arose that could not be resolved despite efforts by Most Wanted and myself. Though the show not happening as originally scheduled is in absolutely no way my fault, I would like to express my heartfelt appreciation to the fans in Moscow that have been so patient and shown me so much love. I look forward to finally rocking Russia (under different circumstances) in the near very future.

в переводе - шоу не будет, полностью по вине тех кто приглашал...

А по поводу организации, просто когда ты за что-то берешься и кому-то что-то обещаешь это нужно выполнять
