It is not about art, or anyway not art like we think of it. It has to do more with a person that can not be living in the past all his life. He is not in the oldies circuit, he has great new music every couple of years and he never denied his past, it is just that too many new songs are in the mix. I wish he could play 3-4 hours and play all the oldies and the new, but since this is not the case, I will go for the new songs. After all he has being allowing live recordings and you can hear all the great songs from the great eras, several hundreds of times.
You know it reminds me of some of my old aunties that still see me as a small kid and ask me about those days, games I played and the same old, like I have never grown up and have new interests. Like going to a gallery and seeing he same photos or paintings for the second and third time and wondering, where is the new staff, why is he still bothering us with the same old things, no matter how good they are.
Yes, I understand that this is a live experience and all the examples I use are not, but still you get the point. I hope!
