And the hardest of Hard Bop. The 50s-60s BN, Prestige, etc. stuff that "we" revere on this board as music for "listening" was in its time just as often as not hardcore inner city, social, bar music. Some people came to listen, but just as many, if not more, came for social activity and just used the music as their ambiance, for the not least of reasons that it was music that was in sync w/the rhythms and textures of their everyday life. They didn't have to sit and "think" to get it. It just hit them naturally where and how they lived.
I've seen whores & johns, pushers & junkies, lovers and theives all doing business while Red Garland & Marchel Ivery played some of the most beautiful, swinging, serious jazz I've ever heard in my life, and nobody, nobody present thought it odd that it was that way. And I'll bet something of lasting value that it was once upon a time that way in every city that had a real jazz scene.
