A blowing session????

I’m a pretty big jazz fan.I truly enjoy Bop and jazz from this era. Question, and perhaps this is not truly accurate/appropriate, is ----how much of this stuff is simply a ’blowin’ session from the artists who are playing the brass instruments, particularly the sax??

IOW, if you have heard one great blowing session, maybe you have heard them all?

Listening to ’Trane, Miles, Parlan, Vick,et al, what are your thoughts?
