I stumbled across this “quasi-field-recording” in July of last year, notes say the album title refers to a Dutch term from the seventeenth century and usually refers to the practice of painting directly from life. Again from the notes on Internet Archive:

Composed, preformed, recorded and mixed by Udo Gerhards between February and June 2020. Most of the work on the album was done during the Covid-19 lockdown period in Munich between March and May of 2020.

I haven’t yet listened to them beyond this album but here is their Bandcamp page.
