Thanks Flurin for the details on this Intakt release. Unjust Malaise collects a lot of his best works and has very good notes from Mary Jane Leach. I especially enjoy The Holy Presence of Joan d'Arc on that one, but all tracks are quite something. That release got me seriously interested.
If I remember correctly, this interview of him is also quite fascinating:
There is a recording of one of his pieces Femenine on the Finnish label Frozen Reeds which is also very nicely done. And they also released this track: https://frozenreeds.bandcamp.com/album/joy-boy
