André Stordeur was a Belgian musician.
To be honest, I’d never heard of Stordeur.
He did the soundtrack to Office Baroque (1977) but that’s not on YouTube.
There is, however, a fine selection of his recordings by Sub Rosa Records on YouTube.
Once again it is clear that electronic popular music (Telex) and electronic art music (Stordeur) are miles apart. That there is no overlap in audience nor in historiography between the likes of art music electronic music practitioners such as Stordeur and counterparts such as Telex who work in the popular idiom.
