+1 Ann Power’s article as mentioned by @tomic601.
Ann Power is about as eloquent and insightful an observer of popular music as exists today. Her article comparing the minimalism of both Blue and Kind of Blue, among other insights, is a great read. 
Highly recommended!
Just thought to add some Blue history to this thread

I'm sure bdp24 can add additional color to this. Just another period of music that will never be matched.
good mentions of other articles, thanks.

here's the link to Ann Powers' NPR article with intelligent observations of Joni Mitchell and Mile's Davis
