Music with a message doesn't have to be boring and Australian duo Left. are living proof. Their single 'IOU' isn't merely about returning something borrowed from another, it's "a statement against slut shaming, and the degradation so many women experience simply for being women" - a subject that's not only rife within the music industry, but as a society at large. "Power lives within us," the pair said on their SoundCloud page "and no one can take that away from us."

The track is taken from their forthcoming EP Heart Shaped Vein and follows their debut album Sirens which was released in February and available now on iTunes.
