(Unsounds)
There are records that just defy any description, such are their variety and multi-faceted sound: this is one of them. “Kraakgeluiden” is completely based on live improvisations recorded in various combinations of a lot of musicians playing squats (please read the notes for further explanation), generally experimenting a lot and having a sincere good time.
