That’s kind of awesome! I have a bunch of home lab stuff, but have been putting off buying a domain (I was a broke college student when I started my lab and half the point was avoiding recurring costs- plus I already run the DNS, as far as the WAN is concerned, I have whatever domain I want). My loose plan was to stand up a certificate authority and push the root public key out with active directory, but being able to certify things against Let’s Encrypt might make things significantly easier.

I’m not in a place where I can compare it to the artists you’ve mentioned, but maybe check out Ben Prunty? He’s got a bunch of stuff in his catalogue (including an album that’s meant to be on the darker side), but I think he’s most known for the FTL soundtrack, which I’d probably describe as space, but pensive and curious.
