IMHO, Terra Inc., I would not say that any reference to jazz is "completely nonsense"... as you defined maybe too hastily...

I quote a reply that was supplied in another forum and that I share wholeheartedly, giving also more historical depth and context to this term...

"..."Schräge Musik" in context with jazz might come from the derogative meaning (use) of "schräg" describing jazz by German propaganda. Maybe due to the improvisation in performing jazz in contrast to classical music, where you have to play your part by strict rules. And also that it might have sound unconventional, schräg. In other context "schräg" has no derogative meaning at all, just sloping, slanted. So in fact it was playing with words, 1. using their actual meaning (slanted guns),, and 2. their unusual, unconventional aspect, not playing by strict rules (like jazz), and 3. it could as well be a tongue in cheek reference to the unloved (by the officials) so called "Negermusik" (negro music). So it was not the reference to jazz itself, but the meaning that was imposed officially."

Being open to other's opinion is not a weakness, but a strenght...
