There are so many different forms under and within the Jazz title or genre...The latter 3 handful of examples which I'll list are strictly primers...once you listen to what you find of theirs, go from there toward the deeper, the core, and the orignators. **Ella Fitzgerald ~~ considered by many to be THE Standard. Was to Jazz what Aretha's done for Soul.
Sade (with her band) ~~ Although oldschool purists knock 'em as "SmoothJazz," their authenticity is legit! Listen to "The Free Design" by Stereolab. Falls under another "type of" Jazz...perhaps bossa-nova affiliated.
"Hearts For Sale" (Rolling Stones) and "Rockin' At Midnight" (Honeydrippers) are both Swing and Blues-based.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
