Though he’s (naturally) remembered for his music, Kurt Cobain was a prolific artist in all forms. He was always interested in painting and drawing as a kid, and according to Montage of Heck director Brett Morgen, Cobain kept making art even during the depths of his heroin addiction. “You can’t look at his paintings and not see self-portraits of an addict struggling,” he said. Cobain’s visual art offers fascinating insights into the iconic musician, and many of his works are displayed in the HBO documentary. W Magazine recently ran a feature on the Nirvana frontman’s art, including several pieces that have never been published before. See all of them on their website, and look for Montage of Heck on HBO May 4.
