Most darkpsy I've heard is unmusical, extremely repetitive, monotonous, boring and irritating. I haven't checked much names, but I've been to a few parties. It sucks.
Yet there is this Ghreg on Earth guy, and while he isn't perfect and resorts to repetitive and annoying sounds once in a while, he mainly represents what I think darkpsy should be. Clever, brooding, a tad evil-sounding, powerful, yet atmospheric, and not forgeting melodies and the musical aspect of... music.
So... anything similar I could try out ?
