Kind Of Blue
Totally reeled me in, in the spring of 1998. I had found the Columbia Years boxed set at the library, ON CASSETTE! That got me started, so I bought my own Kind Of Blue and then I never looked back!
I completely pursued all the Miles I could find for about a year and a half, then started delving into the music of his sidemen, and so on. Now I've probably got about 3000 or more jazz cds. It used to be my main focus and I ignored rock/pop for awhile. But now I spend my time listening to both about 50/50.
I'm glad I started listening when I did, as it was around the same time that the jazz reissues market really started cranking out the remasters. Because of this, I was able to avoid most of the older issues and get the newer 20/24 bit remasters.
But, I've also learned that just cuz it says 20/24 bit remaster, doesn't always mean you're gonna like what you hear. I now know more about whose mastering work I like and don't like.
