Writing on her blog, Marina said: ""Electra Heart" epitomises and embodies the lies, illusions and death of American ideologies involved in the corruption of self."
Pretty standard fare.
She goes on to say that the moody, ethereal ballad is an album track and will be followed next Monday by another new song.
The song's video features Marina singing into a mirror before hacking away at her hair and gazing thoughtfully at the skyline from a hotel balcony. We think this probably has some deep and significant meaning but we've yet to work it all out to be honest.
