In the summer of 1978, performance artist Esther Ferrer took part with her colleagues from the music group Zaj in the group action titled El tren de John Cage. A la búsqueda del silencio perdido, which unfolded over three days in Bologna (Italy) under the coordination of artist John Cage. Ferrer appeared in a train wagon, filling the space with threads and mapping out a path connected to time and its representation. The action was named El hilo del tiempo. Forty years later, Denbora-Hariak / Hilos de Tiempo invites Esther Ferrer to perform it again as the axis of a project examining her work with threads and numbers, the way that she has used lines of thread and numerical games to measure, delimit, represent and transform spaces, times and even her own body.
