In order to fully break down what I'm looking for I'm going to use rock music as an example.
When I was a kid I was really drawn to edgy nu-metal (I guess) music like Linkin Park, Godsmack, Disturbed, etc.
After that I got less laughably edgy shit like Nirvana.
Then, years later, I became obsessed with post-punk almost to the point of jerking off to it.
The myriad of post-punk groups that I listened to, which didn't really have all that much in common, all had the following unifying elements:
Tasteful edge (at least more tasteful than Disturbed); Relatively obscure (your average high schooler does not know about Killing Joke); and experimental.
When I was first getting into electronic music on Sup Forums, I thought that electronic artists like Aphex Twin, Autechre and Burial would scratch that itch.
I have no idea if this is anything near what you're after but it's the first thing that comes to my mind when I hear edgy and it's relatively obscure (and I unironically like it) youtube.com/watch?v=jvlvWnz2-bY
