Thanks! Yes, I have been listening to Nadja Lind / Klartraum for some years now. I found her on Samurai.fm - do you still remember that web site? Must be like 15 years ago or so. It was always a struggle to stream music from this japanese web site, because the internet was not fast enough back then! Unbelievable today...
I was quite surprised by this new sound from Klartraum. Nadja is usually more a House/Techno DJane, while Helmut is usually the one with the drone sounds. But I like it. Just today a few more new tracks were released:

Its also really cool that they put all their tracks on YT for free. Too bad not many people listen to it there.
