The original "Fantasy" opens with a steady organ drone and Lizzy Plapinger's vocals. The layers of vocal harmonies and percussion steadily increasing, taking a full minute to become anthemic with it's stuttering toms and stomping kicks (in true MS MR fashion).
The MØ / Vindahl remix has its focus on space. The build is reverbed vocal cut-ups with the occasional pitch shift. Piano chords ring and faint strings run until the verse gets any play. Here's the real gem of the remix: a natural consequence of focusing on Plapinger's vocals and massive space took the song to a nostalgic pastiche: putting the duo into a Delorean and sending them to 1987, where drum machine claps, smooth synths, and delayed palm-muted guitars are par for the course. What's wonderful is that the chorus brings us back to the present with it's heavy sidechain compression, pitch-shifting drums, and integral sidestick claps.
You don't need the flux capacitor for this fantasy.
