In wake of the terrorist attacks in Paris, Prince has postponed indefinitely his 16-city solo piano tour of Europe that was scheduled to start this week.
His Piano and a Microphone Tour was unplugged, according to his Twitter account that links to a website announcing the postponement of his Vienna gig and the entire tour.
Prince was scheduled to play two nights in December in Paris at the Palais Garnier.
He had already postponed sales of tickets for his U.K. concerts because of ticket touts asking exorbitant prices.
Because of the Paris situation, other acts have canceled European shows or tours including U2, Foo Fighters, Marilyn Manson, Motorhead, Papa Roach and the Deftones.
