Her voice was deeper, richer, more eccentric than BBC Sound Of peers such as Little Boots or La Roux, and the succession of singles milked off debut album Family Jewels (including Hollywood and I'm Not A Robot) felt like the output of a 21st-century post-punk pop band, not a solo girl working cleverly in a studio environment.
With its fast-forward energy, stroppy attitude and killer chorus, Bubblegum Bitch, the opening track on album number two, makes the rash promise that Marina will pick up from where she left off. Then comes recent single Primadonna – classically melodic but determined to drag us onto a dancefloor where Katy Perry holds court. Heavily produced and garlanded with hooks like cheap earrings, it's what you get when you co-write with producers-for-hire.
Homewrecker and Radioactive follow suit; elsewhere there are too many fillers. She's not lost to us yet, but Ms Diamandis has entered dangerously generic territory.
