Rune Lindblad (1923-1991), who was an engineer and a painter, and also a single father with a son in the late 1950s, started his sounding experiments as early as the first years of the 1950:s, without prior knowledge of similar experiments being conducted in France and Germany. He kept on composing against the wind all the years up to his premature death in 1991. In 1957 at Folket Hus in Gothenburg, he gave a public performance of his earlier works. Critics slated him brutally and described his concrete music as a "fad" and "pure torture." Rejecting the concert hall, Lindblad began experimenting with optics and sound.. He also served as a teacher of electronic composition, and some of the most renowned Swedish composers of electroacoustics have had him as their primary teacher and guru.
