Erkki Kurenniemi (born 1941) is one of the most important characters in the history of Finnish electronic music. His mother was Marjatta Kurenniemi, the famous author of children's books. Erkki Kurenniemi founded an electronic music studio for the Department of Musicology at the University of Helsinki in the early 1960s. Alongside working on media art, happenings and short films of his own, Kurenniemi built several electronic instruments for himself and also for other people, such as M.A. Numminen, for whom he created first a "singing machine" with which Numminen participated in a singing contest in 1964, and in the late 1960s Sähkökvartetti ("The Electric Quartet"), which is heard on M.A. Numminen's track 'Kaukana väijyy ystäviä' (1968). An excerpt of Kurenniemi's own composition 'Dance of the Anthropoids' (1968) was heard on Finnish progressive rock band Wigwam's 1970 album Tombstone Valentine.
