Magnús Blöndal Jóhannsson (1925-2005) was a pioneer of electronic avant-garde music in Iceland and composed the first Icelandic music in the twelve-tone style of Schoenberg and Webern. His piece Elektrónísk Stúdía (1959) is also the first electronic music composed in Iceland.
Born in Langanes, he moved to Reykjavik at the age of five. He studied the piano at the Reykjavík College of Music from 1935 to 1945 and then continued piano studies, conducting and composition at the Julliard School of Music in New York from 1946 to 1954. In New York he heard the new styles of the 20th century, he came in contact with Edgard Varese and read books about Schoenberg and Webern. He didn't become influenced by electronic music until he heard tapes from Europe, sent to the Iceland National Radio, where he worked 1956-74. When composing his early electric compositions he used the only equipment available in Iceland at that time, which was a very limited and primitive, owned by the National Radio.

His best known composition, Constellation(1960), was promoted by Karlheinz Stockhausen in a radio programme about electronic music in 1964.
