This thesis is focused on the analysis of the artistic creations of the American musician and frontman of the group Nirvana, songwriter and artist Kurt Cobain, who was active in the eighties and nineties of the last century. Fine art and music share compositional principles such as harmony, balance and rhythm. Many cultures throughout history have also connected music and visual arts, and this connection has been maintained in modern society as well. The theoretical starting point also includes a review of the artistic creations of musicians and artists such as Marilyn Manson, David Bowie, Rick Allen and Josef Albers. The artistic techniques used by Cobain are defined, and four works are analysed. Kurt Cobain was a man who struggled with depression and addiction. Famous artists with bipolar disorder included Vincent Van Gogh, Edvard Munch and Jackson Pollock. Cobain was involved in art all his life, and in addition to writing lyrics and composing, he also created works of art. He was involved in art all his life and, in addition to writing lyrics and composing, he also created visual art. The analysis of his art reveals that the creations followed the themes of his lyrics, and he expressed his feelings through a dark sense of humour. Frequent motifs of Cobain's works were dolls, marionettes, human anatomy, unusual characters and self-portraits. He mainly used surface modelling techniques such as painting and drawing. He painted with acrylic and oil, drew with pencils and felt-tip pens, often combining techniques. The analysis of art works and techniques leads to the observation of the interweaving of Kurt Cobain's music and art. Fine art created by musicians shows emotions, moods, life stories, loved ones, just like fine artists who create messages and show what they want to show to the whole world.
