Edvard Munch, a.k.a the dude who did the Scream is a Norwegian Expressionist with a very bleak outlook on life. His sister and mom died when he was a Kid, his dad was overly Religious which added to his anxiety, and he was sick a lot. These events largely influenced his paintings, which all have an anxious and morbid feel to them. Death in the Sick Room, the Dead Mother and Self Portrait between Clock and Bed are all brilliantly done and damned depressing. Even the Dance of Life which sounds happy, has some Seriously dark undertones. As he Matured as a painter, and possibly as a person, his Paintings became less bleak, more colorful and more focused on Nature. Moonlight is about as Pretty a painting as I've ever seen, and surprising considering it is not what you would expect from the painter. Girls on Bridge is a happy, brightly colored Painting of, well, girls on a bridge.
Bottom line, Munch was an Awesome painter and if you find his early works to depressing, his later ones will brighten your day. He had a sad and Vulnerable soul, and he willingly shared that with us, much to our benefit. His Voiceless pictures speak volumes no matter what phase he was in and he seemed to be a bit of a Prophet when he said:
"From my rotting body, flowers shall grow and I am in them and that is eternity."
