It depends on what a museum is. Some people get excited by looking at great paintings and saying "I'd like to do that." Does that make someone musty? Why can't we find artists who can paint like they did in the Renaissance period and have that reflect current values?
There's too much emphasis on time periods and less on quality of the product.

Why not honor traditions? Why say they don't relate to the current emotions and ideas?

Why is there such a preoccupation for being as the French say, "Au courant"?

The reasons we like folk music (the collective "we") is that it is a tradition that we honor.
If you don't honor tradition, that's o.k. too. But that's not then what folk is about.

Tradition exists because the best artistic product is preserved, honored and recognized as quality. People are affected by traditions in music because they have something that's unique but substantial. When you listen to a performance by a traditional folk singer, they are expressing in a unique way a value from another time.   This doesn't mean it doesn't translate into contemporary times.

There is this cult of "originality" and "individuality" that implies that unless it is somehow
connected to contemporary ideas and "sprouts out of the ground" like a snowflake that somehow it's derivative and not valuable. Most of these styles of artistic proclamations
emanate in a specious way. "Look at me, I'm different!" But this difference is not really
evident because we are all connected to the past artistically, ideologically and just because we are creatures of habit.

An artistic performance defies time periods.
