Then what is it that you do see? Because I see references to specific releases like this, with an audio embed following them right after:
> Hear below Stockhausen’s “Kontact,” Henry’s “Astrologie,” and Bayle’s spare “Theatre d’Ombres” further down.
There are 3 embedded audio widgets, with a total playing time of about 55 mins.
That seems unlikely to contain 476 tracks ... and nowhere do I see any actual list of tracks (other than the mention of 3 that you quoted).
Aha, the actual list is here: https://ubu.com/sound/electronic.html
