My Bad Sister are Identical twins Polly and Sophie Duniam, an all-singing, all-dancing, turbo-charged, double act making big waves on the rave scene.

The East London-born bad girls mash-up a cockney-style delivery with catchy melodies and heavy bass, they call this CabaRave!

Performing and recording for six years My Bad Sister ‘s lyrical delivery, razor-sharp mirrored choreography and boundary-pushing subversive themes have earned them some serious respect on the scene.

MBS are a creative force to be truly reckoned with, a unforgettable live act.
