 Kupkovič called this kind of concert a "Wandelkonzert" (meaning "walking concert"), and "Wandelkonzerte" have often invited comparisons to John Cage's "Musicircus" events.The idea was expanded for "Klanginvasion auf Bonn" (1971), for which 150 musicians played at various venues in Bonn over the course of twelve hours.There is some similarity here to Trevor Wishart's community pieces like "Forest Singularity".
