Nam June Paik presented Random Access in his solo exhibition at Galerie Parnass, Wuppertal in 1963. Fragments of magnetic tapes unwound from a spool were attached to the wall, and visitors with a metal tape-head separated from playback equipment could scrape the point they wanted to listen to. After this exhibition, the playback head was lost and Paik reproduced it in 1964. The reproduced playback head, battery cable, and headphone connected to circuit board are assembled in a wooden box.
