It may be the the wine I just drank this afternoon, but I started thinking while listening to Oliver Nelson's "Blues and the Abstract Truth" that this is a recording that should be a requirement for high school students to listen to in order to graduate. It is just such a great album from start to finish. If you haven't listened to this, you are lacking something. I bet there are individual favorites for others here. Which one(s) do you feel are mind altering, life changing, and important to others that everyone needs to listen to at least once in their lifetime?
