"Postcards from Plateau of Leng" is written to function as a sort of soundtrack for HP Lovecraft novel "At the mountains of madness." Hence, it is structurally bound to the novel itself. Because of its length the song is divided into three parts. Stylewise, this song is a combination of classical, electronic, ambient and even ethno.The home-made PVC-flute samples are from Herman Witkam. The version presented here is to be considered as work in progress.
