Is it churlish to question whether some musicians should be called "jazz" musicians? I doubt it keeps them up at night and in fact, calling yourself a jazz artist is probably a bad career move. It's not a question of chops and whether someone deserves to be put under the jazz umbrella. I mean, who's the arbiter? And who really gives a crap?
Youth is a time when the debate about who is "keepin it real" is even more extreme and heated than it is among us elderlys. The DIY movement prefers vinyl to mp3 and I imagine a solid campaign behind 78's with a little surface noise would get traction.
Yea, there's always a lot of "fronting" about realness. Maybe it's the physical needs charged up by hormones run amok, but however you explain it, intensity and challenge are highly valued in the young. And, when everything is so available, difficulty and scarcity create value; create charisma.
I know, this is beginning to look like the "5 reasons not to use the word jazz" list, but let those who care be conscious of how they throw the word jazz out there. Keep in mind that music that soothes rather than disrupts and lulls rather than challenges will get the swift boot by young people. Give em Trane, Cecil, Rex Stewart and Oscar Pettiford. That might shake some adolescent trees.
