==Wandelkonzerte==
Kupkovič has probably become best known for his experiments with the concert form in the 1970s. In ''Musik für das Ruhrfestspielhaus'' (1970), he arranged forty performers to play a number of pieces in a concert hall in [[Recklinghausen]] over the course of three hours. The pieces were played in various parts of the building, some of them at the same time. 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]]''.

Some of the music played in the ''Wandelkonzerte'' was written by Kupkovič himself, some of it by other people. Much of it, however, was music by older classical composers which had been altered and adapted by Kupkovič. This process is typical of Kupkovič's instrumental works, and can be seen in such pieces as the series of four ''Präparierte Texte'' from 1968. These pieces take quite insignificant parts from well-known pieces of the past, such as the [[viola]] or [[bass drum]] parts, and isolate them, thus making central music which in its original context was incidental and often barely audible. ''Präparierter Text 1'' is adapted from the second movement of [[Johannes Brahms|Brahms]]' [[Symphony No. 1 (Brahms)|Symphony No. 1]], and is for violin and [[magnetic tape]]; ''Präparierter Text 2'' is adapted from the first movement of [[Wolfgang Amadeus Mozart|Mozart]]'s [[Symphony No. 41 (Mozart)|''Jupiter'' Symphony]] (No. 41), and is for [[flute]], [[trumpet]], [[timpani]], violin, [[cello]] and [[double bass]]; ''Präparierter Text 3'' is adapted from the fourth movement of [[Ludwig van Beethoven|Beethoven]]'s Symphony No. 9, and is for [[cymbal]], bass drum and magnetic tape; and ''Präparierter Text 4'' is adapted from the ''Ricercar a 6'' from [[Johann Sebastian Bach]]'s ''[[Musical Offering]]'' and is for chamber [[orchestra]] (a version for full orchestra followed in 1970).
