A lot of art made during difficult circumstances should be hidden in a closet until the crisis to which it was a response has been resolved. Then the artist should take a fresh look at it to see if it stands up on its own merits outside of the context in which it was created.
Much art created during hard times serves a cathartic and healing function as well as being an artistic expression. It's sometimes hard to separate the two. I don't particularly want to listen to some guy working out his angst.
