Johnston’s songs have been covered by several hundred artists, including David Bowie and Tom Waits. The late Kurt Cobain mused that Daniel Johnston is the best songwriter in America. In 2006, his life was documented in the award-winning film, The Devil and Daniel Johnston, and his painted illustrations were exhibited in the Whitney biennial. Johnston had a lifetime battle with mental illness, and medication prescribed for this condition damaged his liver requiring multiple hospitalizations. He died from a heart attack in his sleep before the morning of September 11, 2019.
