mainland music band?

Hi all.  Happy Tiger Year!

Does anyone out there know of any musical acts based in mainland China?  Preferably Chinese citizens who sing in Chinese (but absolutely welcomed to sing in English or a blend of both)?  Fairly commercial, catchy, mainstream pop in nature.  Also, emerging.  Not a super established act.

I'd be grateful if you could send me any examples, website, suggestions of any should you know of any.  It's for a performance in Shanghai in August.

Thanks!  Many blessings and much success to everyone this year!
