Fred P’s Soul Life Connection pops into my mind. I really like him as a DJ and his productions are deep as hell. You should check his own label Soul People Music.
And of course Larry Heard aka Mr. Fingers with his label Alleviated is the next what who comes into my mind.
Tristen runs the magical vinyl only Aim, based in Berlin and featuring artists like Christopher Rau, Moomin, Oskar Offermann or himself
