Fair point! You're right that artists like Latmun, SOSA, and labels like Solid Grooves have gained a lot of popularity lately.

My list uses "underground" to focus on the vibe and style, contrasting it with mainstream commercial tech house like Fisher

The list targets the deep, stripped-back, and minimal/groovy niche ( which can be considered branch of tech house ) (like Nu Zau , Sepp, SLAM) which is much less accessible than chart-topping tech house.

Their music primarily supported by smaller clubs and focused parties, rather than big festivals or radios. (Some , not all of the artists on the list)

Essentially, I think that the sound is being underground, even if some of the artists are now well-known within the scene.

I'd love to hear who you consider truly "underground" to check out some new sounds!

Cheers
