This is good jazz and both tracks are good.
Youd probably like the Voodoo Vince soundtrack as it goes big on new orleans jazz. Voodoo Vince: Main Street:https://youtu.be/M-Y_iWMuIag?si=VcTY6spTeG_Jk5LV I also think youd like Grim Fandango if you like that atmosphere and jazz of course.
I have actually been intrested myself in making jazz so if you have tips id love to hear them
