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. Later, for the exhibition, Sehen um zu hören, at the Städtische Kunsthalle, Dusseldorf in 1975, Paik reconstructed this work and called it Random Access Audio Tape. This work consists of a chipboard to which magnetic tapes were attached, instead of a wall, and a playback head connected to a portable cassette player. Like the first work, viewers could directly scratch the tape and play the sound.
