I think folks are just listening to the wrong jazz!

Here's a few modern jazz or jazz fusion song recommendations from me worth checking out:

'Ramen! Yes!', 'XYZ', and 'Balloon Pop' by Hiromi's Sonicwonder (also credited separately as Hiromi and Sonicwonder)

'Desire', 'Knowledge', 'Prologue', and 'Fists of Fury' by Kamasi Washington

and it's bossa nova which I guess is technically samba not jazz, but I say close enough to still recommend 'I Took the L' by John Roseboro

Bonus recommendation if you're open to heavy music (this is death metal jazz fusion!):

'Eb (D#)', 'IQ69Exaltations,' and 'deBroglieNeverExisted' by ByoNoiseGenerator
