Song in a Minor Key's similarities to H.P. Lovecraft

Song in a Minor Key is a short story by C.L. Moore that is classified as Space Opera, but reminded me a lot of the H.P. Lovecraft short stories I read for the New Weird. Song in a Minor Key and What the Moon Brings are both very quick reads that leave the reader generally uneasy. Both short stories provide great amounts of detail of the moment you're currently reading, but lack any detail of context. What the Moon Brings creates a strange version of our Earth where the low tide brings out not sandbars or tide pools, but a giant beast. There was absolutely no context provided by Lovecraft on how the beast or the narrator got there, but there was beautiful language describing the scenery, the lighting, and the mood of the world where the beast and narrator existed. I found that Moore did a similar thing in Song in a Minor Key. While there was little context on what the time period was, it was clear that the universe we were in was a very peaceful Earth and advanced space travel. While we know that the narrator was banned from Earth for his violent actions (which is definitely an ideal future, as violent acts happen every day in this time period), we can't gather what he really did. There is also a subtle anxiety through the story, as if it's the calm before the storm. Northwest Smith (which isn't even his real name) is relaxing in a warm, sunny, beautiful valley but he keeps dwelling on how he shouldn't be there, how uncomfortable the gun pressing against him was, how what he did was terrible, and how what he did was inevitable.

I found the world building in both these stories really interesting. I was grounded enough to understand that it was a different world from my own, but I wasn't given enough details to be fully comfortable.
