The Radiola Improvisatie Salon was a programm by Willem de Ridder. His radioprogramm (1980 era) was to play music people would send him on cassette, with no advance listening, just open the enveloppe on the air, play the tape. I posted a tape released by the programm a long time ago, and also their audio newsletter on tape. Today its a tape with six different composers, separated per composer, not per track (no titles given) and we have Enno Veldhuys, Arts, Hessel Veltman [sic], Van Ede, John Zandijk and Wolf Zimmerman. Lots of great synth based music.
