Musicians often "cover" songs recorded by other artists, developing a new interpretation of it. Artist Jeff Wall "covered" a work by Hokusai with his A Sudden Gust of Wind (after Hokusai). How does Wall’s work create a dialogue with Hokusai’s? How do the differences in their works speak to the viewer about the intentions or purposes of both artists? How does this "cover" represent the theme of "Art and Art"?
