Mysterious NYC duo ASTR have dropped their debut single 'Operate'. Razor-sharp hip-hop snares cut through rumbling R&B synths and bass, conjuring up images of femme fatales and anti-heroes' street-lamp shadows bouncing off pavements.

Although there is a bona fide mood to 'Operate', what you ultimately come away with is a catchy chorus, which could be straight off a Rihanna or Rita Ora single, and will be lingering on your mind for the rest of the day.
