Re: ...for the jazz cats ...
"the streets"?...Bop was born out of human curiosity, plain and simple.
Anyone who's played an instrument for any amount of time has played with themes and generally "noodled", discovering new sounds from their instrument.
Bop just took that to an art form and eventually, a varient of the Jazz idiom.
Hard Bop simply describes attitude.
In the 90's we would've called it Aggressive Bop.
Watch how Blakey plays and you'll see what Hard Bop is all about.
