Not heard this before and conflicted based on the subject matter. Musically 5/5. Concept 1/5. I'll give it a 3/5.
I have heard the name before, but have no idea what to expect. This bassline is great, and speaking French over things usually makes them at least 37% cooler. Breathy French female vocals are hot. The orchestration elements are excellent. I could listen to this for 2 hrs 52 mins. That was incredible! I have never listened to Serge Gainsbourg before and I have to say I am know looking at his disography for more! 4 / 5 stars.
Creepy lush music.
