In March 2013, the band was not allowed to perform at a music festival in China due to unspecified "political reasons". In an interview in June after performing the eight albums of "The Catalogue" in Sydney, Ralf Hütter stated: "Now we have finished one to eight, now we can concentrate on number nine." In July, they performed at the 47th Montreux Jazz Festival. The band also played a 3-D concert on 12 July at Scotland's biggest festival – T in the Park – in Balado, Kinross, as well as 20 July at Latitude Festival in Suffolk, and 21 July at the Longitude Festival in Dublin.
