The promoter of Aerosmith's canceled May 11th show in Jakarta, Indonesia has no idea why they pulled out and says he hasn't been told what security concerns they had.

Sarah Deshita of Ismaya Live says, "Our (preparations) were 90 percent ready when we got their cancellation letter one week before the concert. We had got police permits and offered Aerosmith the best security we have, including having a lot of Marines at the venue... We're unsure of the safety concerns they're citing in their statement."

The cancellation came after counter-terrorism police said they'd foiled a planned attack on the Myanmar embassy. Lady Gaga also canceled her show there after it was threatened by a hardline Muslim group who said her performances were immoral.

Aerosmith wrap up their Pacific Rim tour on Wednesday in Manila, The Philippines.
