BERLIN.- FischGrätenMelkStand (herringbone milking parlor) is the title of the final project at Temporäre Kunsthalle Berlin, curated by artist John Bock. Like previous artist-curated exhibitions, his complex concept is based around an emphatically subjective artistic viewpoint. For FischGrätenMelkStand, John Bock has developed a masterful meta-structure within which he installs works by 63 artists, architects, and composers. Besides installations, films, models, and sculptures, there are also historical film props, music scores, books, and fan items. The herringbone in the title refers to the symmetrical design of this type of automated device used in dairy farming. The eleven-meter-tall steel construction creates a range of spatial situations over four levels, linking the individual works into a kind of Gesamtkunstwerk, or total artwork. The dimensions of the walk-in installation are almost those of a Berlin tenement
