Band Says Beijing Canceled Concert Over Tibet

A band called Oasis was set to perform in China, but when it was discovered a member was involved in a free Tibet concert they were told that they would not be able to perform. The reason given by Chinese officials to the public was for economic reasons.
This seems to hold true to class discussions about Tibet be a sensitive topic by the government and censorship by the government.
