“Years” (2012) by Alesso and Matthew Koma was brought up as an example of effectively using layers of narrative sounds overtop an already fully-featured musical passage with a strong structure of its own. In your work, you’ll of course need to focus on the listenability over danceability (i.e., music for ears and attention, not the dance floor), but this video includes several useful moments to serve as “case studies,” including multiple layers of independent musical passages laid over each other.
