The through-line: the kick never leaves.
Across four marked seconds spanning 1977 to 2018 the tempo barely moves - a metronomic 123 BPM, every section landing in the 120-140 cluster. The keys lean minor (A, G) with one bright C-major outlier (Donna Summer), and the timbre is overwhelmingly dense & textural: layered synths and sidechained pads rather than open air. This is a listener who hears the French-house lineage as one continuous loop - Daft Punk and Stardust filtering the disco of I Feel Love forward into One Kiss.
