Now it's true, some gallerists are more articulate explaining a given artist's work than the artist himself… But it's generally more FUN to hear directly from the brain that made the work.
Don't be shy, take an artist to lunch.
Believe me: most artists LOVE to tell you about their work, particularly a specific piece.
They live to create, they want you to "get it."
