I'm no big blues fan either, but about its use in travels:
I spent a few years in Afghanistan, way back when the USSR was still a thing and the moudjahedin were seen as freedom fighters. Pre-Taliban times, music was everywhere and particularly in cars. I would be exposed to hours of Pashtoon musac
during car trips, and it struck me as being closed to the blues: simple harmony with standards and predictable chords; not much virtuosity in the instruments but a chorus here or there; a lot of emphasis on the voice and on the emotion the voice can carry; and the fact that all songs would sound pretty much the same.
So I recorded a couple of blues tapes at home, and during subsequent travels I played them again and again instead of the Pashtoon thing. Afghans just LOVED them...
