The 'Hollywood' singer posted a video to new track 'Part One: Fear and Loathing' on YouTube earlier this week, which stated: "ELECTRA HEART: THE START."
"Basically Electra Heart is a story," she told Popjustice. "I don't even know if it's going to take the form of an album yet, but it's a really cinematic '70s Americana-type film and each part of the story comes in Part One, Part Two, Part Three.
"I think a lot of people will think Electra Heart is an alter ego or something but she's not, it's kind of basically a vehicle to portray part of the American dream, with elements of Greek tragedy and that's all going to be coming out through the visuals. It's hard to explain but I think you'll see it when it all comes together.
"Electra Heart is the antithesis of everything that I stand for. And the point of introducing her and building a whole concept around her is that she stands for the corrupt side of American ideology, and basically that's the corruption of yourself. My worst fear - that's anyone's worst fear - is losing myself and becoming a vacuous person. And that happens a lot when you're very ambitious."
Marina recently claimed that she feels like a failure.
