U.S. rapper Kanye West’s two planned concerts in Russia are cancelled, event organizers announced. The shows were scheduled for October in St. Petersburg, with organizers saying the dates will not go ahead. The announcement follows a surprise decision earlier this year that generated widespread attention.

Organizers did not provide detailed explanations for the cancellations. One outlet reports that the Moscow-based promoter, Say Agency, confirms the cancellation for both St. Petersburg dates. Other reporting attributes the decision to Russian authorities and says they are investigating the organizers over alleged fraud, citing Russian media accounts.

Overall, sources agree on the core outcome: West’s October concerts in St. Petersburg are cancelled. The main point of difference is the stated or reported reason—ranging from organizers simply failing to give reasons, to claims that authorities are involved and investigating the promoters.
