I generally prefer black metal for my day-to-day listening, but power electronics/death industrial/noise is an elite choice, and yes, very relaxing. It is tragic that few people understand the work that goes into it and what real, high quality power electronics/death industrial/noise actually sounds like. Operation Cleansweep, Deathpile, Genocide Organ, Brighter Death Now, Sutcliffe Jugend, Whitehouse, Ramleh, Purient, Controlled Bleeding, and my personal favorite, Alberich:
Alberich-Rumbala
Someone such as yourself might prefer something less intense, like:
Sutcliffe Jugend-Shame
If you cannot understand the beauty in these tracks, I won't be able to help you see...unless I try some power electronics/death industrial/noise adjacent black metal:
Gnaw Their Tongues-Sound The Horns, The Water Is Poisoned!
God I love Maurice De Jong, if I were to meet any musician, it would certainly have to be him.
