More video inspiration

I particularly love the editing used in this music video. It is apparent that whilst the artist is singing in the ballroom there is another video playing at the same time but faintly so she still remains the main focus of the video. I believe that this was used to show the narrative of the song whilst also allowing viewrs to see the artist preform. I am considering using this technique in my own video as it will suit the tone of 'teen idle' given that the mood of the song switches from positive to negative. For example, I interpertate that the lyrics of 'Marina and the diamonds - Teen idle' are to show how the artist feels as if she wasted her teenage years rather than getting herself involved, i.e being the prom queen. So a possible idea to include in my video is to capture a scene of the teenage girl in a prom dress, whilst the main video playing will be of her being a 'teen idle', either smoking or simply sitting at the dressing table.
