Those who can, do. Those who no longer have the time or creativity to do much, teach, share, and enjoy. C'est moi.
My kids see all good music as existing NOW. I agree with them. It's all current. It's all sitting on the shelf in front of them, ready to be cued to match the mood or the need of the day.
I've lived and listened through the last 50 years of music. And while a lot of it is more or less familiar, putting it in a meaningful context is important to me. But context isn't nostalgia (call me out if my show ever gets that way); it's relationships in the now.
Consider this show the living history book you always wanted. The one that goes down easy, and makes it all make sense.
