Can you recommend Jazz for some one that doesn't like Jazz?

Glad you like Madeleine.  I didn't know she's from Athens either. So thanks for that. 

I think one must really like to listen and appreciate the sound of instruments to begin to like Jazz. Take saxophone for instance. Once the listener starts to engage with the tones and rhythm of a really good saxophone player, it gets addictive to an extent. Then the style of the player begins to emerge. Illinois Jacquet is one of my favorite players. Even vocalists will use their voice like they are playing a jazz instrument. Ella Fitzgerald is a good example. Try her album with Louis Armstrong “Ella and Louis”. If you listen to jazz that seems disjointed, think of the artists conducted an experiment like a scientist. Great Jazz artists usually dislike conventional ways of playing. If you are having trouble, start with an artist who has branched across genres, like Ray Charles, try “Soul Brothers”. For a more modern player, try Boney James, Cecil Mclorin Salvant or Diana Krall. Good luck.

Tones and rhythm are probably not enough if one doesn't grasp the significance of the notes being played. This seems to be a major stumbling block for those who do not like Jazz. It apparently sounds like a random jumble of unrelated notes, rather than a cogent expression utilizing a recognizable language. It's difficult to become addicted to something that one experiences as inherently off-putting.
