OK, a bit of backstory with this one. Poppy started out as a YouTube personality. Very distant, almost mechanical, slightly disturbing material. She then started releasing music. Her first album was pretty much electropop in style, albeit rather weird electropop. I have it, it's very good IMO.
Her second album was more diverse, and the last two tracks, "Play Destroy" and "X" both had metal influences. All her new material seems to have this same influence, it's quite a major direction change. She has some great YouTube videos out there. Of all her tracks, X is my favourite, the way she combines her styles works for me.
Here's a rather bizarre interview she did on some American music show.
