The band had to cancel their May concert in Turkey after a mining disaster that killed over 300 people, and their upcoming July 2 show in Kiev has also been called off due to civil unrest.

Kiev's National Corporation of Entertainment released a statement confirming the cancellation, saying, "With much regret we have decided to cancel the Aerosmith show in Kiev on July 2nd. It is impossible to produce this show in Ukraine while there is civil war. We can't ensure safety to the artists, crew and the audience. We can't ensure safety of the equipment."

Aerosmith's Joe Perry called into Boston classic rock station WZLX's host Carter Alan, to discuss the tour. He said that, cancellation notwithstanding, he enjoyed being in Turkey, and noted that Istanbul is his favorite European city.

"It was a drag we couldn't play because of the mining disaster, it was a national day of mourning," Perry said. "But it was a really amazing experience."
