Like yesterday I haven't gotm much clue about one J. Derwort, except that he is from Rotterdam and plays music on home made bamboo flutes, but also calrinet, percussion and special effects. There is a little bit found on the internet and it seems he had a connection to Michel Banabila. The word new age falls. Ouch. But I thought it was quite a nice ambient work after all. I have no idea about the label.
