I don’t hear great art as old and new even though for sure there are different periods and style. Great art rides above the time stream in my opinion. I don’t hear Bach as old and Bartok as new any more than I hear Louis Armstrong as old and Charlie Parker as new. Same with Rembrant and Picasso. I leave that kind of categorization to the pop music world. The point is real ART from an earlier period can even be more meaningful and powerful than a later period so don’t ever discount it is “old” as what you may get out of it may surprise you.
