I disagree.
Jazz is academic and a thinking man's music. It's stuff like metal and head bobbing trash that brings out he primeval beast.
Hey Blo,
I actually only semi-agree with your quote above so please also allow me to add the following.
Jazz, metal, reggae etc are forms of music at the start and at end of the day. All forms require thinking for sure but all also eventually lead to some sort of expression be it head-bobbing, salsa dancing or even feet tapping.
I used to listen to bands like Nirvana when i was growing up but now i also listen to Jazz and latin etc....and i still get the same kind of "high", same kind of "in the zone" type of buzz when i get engrossed and carried away.
Therefore music in general, no matter what, will bring out the good and the beast in anyone who's willing to let go, who's willing to "rock out".
This is my humble opinion and I dont mean to hurt anybody here
