So there was no concept of commercial "Top 40" stations in every town. But why was that, if there was otherwise an influx of the US pop culture paradigms?
So, there were lots of indie labels, but little or no chance of radio play or a regional hit? One is not necessarily related to the other ... 99% of the indie labels in the USA never got any airplay either, but that was what most of them were at least hoping for.
I really didn't think of talking about Germany when starting this thread, but as my major interest was finding out about the differing definitions of pop culture, you're absolutely hitting the mark when asking questions like these.
Of course I can't give any profound first hand account like Ned, no comprehensive picture by any means. Just bits and pieces I read or heard from witnesses of the period.
There were local scenes and bands probably not totally different from the ones Ned describes. At that point (1964-68) the British influence on those scenes was definitely stronger than the US American. The omnipresent word was "beat". From what I know the original fans of this music didn't use the term "rock'n'roll", because it was identified with 50s artists.
Those people weren't political, but they were considered quite subversive, a threat to society. German mainstream society was very reactionist. Partly because there were still Nazis sitting in all kinds of administrative positions, in the police, in the judiciary, in the universities etc. The rest of society was trying to forget or ignore the past (and their own involvement) by resorting to a very clean-cut, idyllic cultural orientation.
The major issue besides the music, as silly as it may sound today, was the hair-style, or more precisely the length of hair. I can't find it now, but I read some letter of a person who was addressing the intendant of a broadcasting company by saying: "`Beat´ is not bad for the youth, it's good... of course the hair might be long, but they wash it regularly!"
Things changed very slowly. The first platform for the new youth culture was not on German radio, but on TV. This is speculation, but I imagine they feared playing it on the radio, because it would have been too offensive and frightening for the normal public. On TV things were kind of more under control. You saw what you had to deal with. The pogram was called "Beat-Club" on Radio Bremen (it says "Radio", but it was a television broadcast) and it started in 1965. That was the first and for some time the only thing that was happening officially.
The rest was underground, so to speak. A very large underground, because a high percentage of the youth actually wanted to hear that kind of music. So live acts, and especially local acts played an important role.
I don't know if the German definition of pop culture really stems from there, but this was probably the very start of modern pop culture in Germany. And while being highly popular amongst the youth it was hardly present in mass media.
Regarding the indie labels: of course the numbers can by no means be compared to the US. This would need further investigation, but I presume they were private enterprises, studios, which saw the demand not so much for national distribution, but from the many beat groups who wanted to record something and sell it to their audience.
I'm sure this all sounds a bit crude. I'm just trying to give a summary to the best of my knowledge.
