Banned! 18 Musicians Barred From Stepping Foot In Certain Countries
Oasis – China: Oasis were "bewildered" when the licence to stage gigs in Shanghai and Beijing was revoked in 2009, due to the band's links to the Free Tibet movement (Noel appeared in a gig for the movement with U2 and Coldplay in 1997). An official later said it was nothing to do with Tibet, and that the gigs were cancelled due to a "tough economic situation".

Bjork – China: For similar reasons to Oasis, Bjork was banned from performing in China for campaigning for Free Tibet. Her song 'Declare Independence' particularly upset the authorities there. She also performed the song in Tokyo and dedicated it to Kosovo's declaration of independence in 2008, which may have led to the cancellation of her performance at Serbian festival EXIT that year.
