I'm amazed that Daturah hasn't been mentioned yet. They're fucking incredible.
Also, Akhmed, Surface of Eceyon, Bossk, Galacticka, Shora, Meniscus, My Sleeping Karma, sgt., SubArachnoid Space, and Ten East all have interesting takes on the genre, generally more psychedelic-tinged than average (as are most things I listen to).
