A while back a discussion emerged on Twitter about composers who wrote drone pieces. My name was mentioned as a likely source of information, which was probably a mistake. But I am interested in drone-based works, and herewith share a few recordings that I have found worthwhile. It is by no means complete in any sense. And many (if not most) artists on this list, like Niblock, Palestine and Radigue, have far more recordings available than I have mentioned here. But it might get you started.
See a glaring omission? Please add your own suggestions in the comments.
