I found this video and I learned some interesting things
about form,composition and arrangement,I recommend it to everyone 
but!
this things (post-bop VS free jazz) about which this guy says in
1:15,2:57,3:24,7:04 etc inspired me to further research.
I’d like to create a list of 50 (or 100 or more haha )
essential songs which are the quintessence of this genre.
PS. I like pianists most (pianos also have strings like a guitar)
because complex chords on the piano sound best
Any ideas and recomendations???
Pliiiiiiizzzzzzz
