Ken Burns' Jazz was what turned me on to Jazz.
I was around a LONG time before that was made, but i never liked Jazz. It was 'too busy' in ways i just did not get. So I totally avoided it.
Until i happened to see some of the Ken Burns program, then watched the entire series. Suddenly i understood what the players were doing, and was hooked.
Now, about 40% of my listening is to Jazz, 35% Rock etc, and 25% Classical.
And NO, Jazz has not diminished my interest in Rock.
I never was a 'metal' type anyway, nor The Carpenters.. LOL.
Jazz did incease my appreciation of more complex music. (aside from Classical, where I was at a pretty deep level of appreciation anyway.)
