I spent two or three months in Germany in 1981, I did an album in a studio called Dieter Dierks Studios, The Scorpions were his big band, I think he managed them or at least they recorded here. Very nice studio for the time, was a double, two bands recorded there at the same time, two 24 track machines in two different studios with IIRC more tracks available in a mobile which I never saw. It had its own hotel and everything, the album never got picked up and the producer never paid the studio so no copies, (sucked anyway

) although there are a few lo fi copies somewhere but I don't have one. I actually saw real flanging done, the engineer had two 2 (I think 2 track) track machines going and touched one lightly with his forearm to get it slightly behind the other one to create the out of phase swish, very interesting, it took him several times to get it right.
I saw the street where the Star Club used to be.
But yes it was a very nice country, people were nice, most spoke pretty good english and at least at the time there were a lot of underground clubs, it was kind of beatnick-y, neat country.
