Leif Elggren (born 1950, Linköping, Sweden), is a Swedish artist who lives and works in Stockholm.
Active since the late 1970s, Leif Elggren has become one of the most constantly surprising conceptual artists to work in the combined worlds of audio and visual. A writer, visual artist, stage performer and composer, he has many albums to his credits, solo and with the Sons of God, on labels such as Ash International, Touch, Radium and his own Firework Edition. His music, often conceived as the soundtrack to a visual installation or experimental stage performance, usually presents carefully selected sound sources over a long stretch of time and can range from quiet electronics to harsh noise. His wide-ranging and prolific body of art often involves dreams and subtle absurdities, social hierarchies turned upside-down, hidden actions and events taking on the quality of icons.
Together with artist Carl Michael von Hausswolff, he is a founder of the Kingdoms of Elgaland-Vargaland (KREV) where he enjoys the title of king.
