I've been re-reading Q posts and think I found something, but don't see how it fits.
Q post #294 asks USSS code name for Hussein [R] and who protects Hussein? [R]
Hussein is Renegade which we know, but [R] also represents Rothschilds. Searching both terms together provides articles on a Renegade Rothschild known as Nica de Koeningswarter.

I don't know how she, Hussein and the jazz scene tie in together, but I think it's relevant that Q used [R] to refer to Hussein and Roths in same question set and this black sheep pops up.
