I shouldn't have to tell you what Faust sounds like. All I need to really mention is that they keep their drawn out, psychedelic, effect-ridden music that they've had for all these years. I would say it's a modern version of their old style, but if you'd release the s/t, Faust IV, or any number of other Faust or other krautrock albums in this day it'd be equally modern, but even then, Something Dirty still works as a fantastic callback without falling into self-imitation.
There's really not much to say. It's Faust, it's great, you want it.
