Jacob Kirkegaard's sound works focus on investigations into the potential musicality in hidden sound layers in the environment. In this context he has been capturing and exploring sounds from, for example, volcanic earth, ice, atmospheric phenomena, nuclear power plants and deserted places. His piece "Labyrinthitis" was created from sounds recorded inside his inner ear. Recording tools used include accelometers, hydrophones and home-built electromagnetic receivers.

Else Marie Pade (1924-2016) was one of the pioneers of electronic music in Denmark. From the beginning of the 1950s, she, in close co-operation with technicians and assistants on Radio Denmark, produced a substantial amount of concrete and electronic music, partly in the shape of independent works for radio broadcasts, partly in the shape of accompaniments to various radio dramas. From 1957 until the middle of 1960s, Pade experienced a productive period in which she created a long series of electronic works and thereby made a name for herself, both in Denmark and to a certain extent in international electronic circles.
