twelve girls band

i like the traditional Chinese music and i learnt from medias that there is a famous band -twelve girls band featuring traditional chinese folk. i currently live in Shanghai. Could anyone offer some advice on where i can purchase any albums of the said band in downtown Shanghai.

hi, I like them too, twelve girls, all in their twenties, with long hair standing before a arrays of Chinese traditional  instruments. They once visited USA and i bought one album of them that time. It should be very easy to find one in mainland China.
