Thanks for that list. I have quite a few of the albums you listed. Some are completely unknown to me and I will check them out.
My definition of Experimental music is not quite as broad as yours. For example, Lustmord - The Place Where Dark Stars Hang and Eno - Ambient 4 aren't albums I'd classify as Experimental. Both of them easily fit into other genres.
Experimental for me is "difficult" music that doesn't easily fit into other genres. By difficult, I mean it's challenging to listen to. Nurse With Wound certainly makes Experimental music most of the time. Hafler Trio. Zoviet France. Fossil Aerosol Mining Project. Some of the early Avant Garde electronic music is still Experimental, such as Karlheinz Stockhausen and Bernard Parmegiani.
There are no hard and fast rules. I'm just saying we have different opinions of what Experimental music is today.
