Beginning in 1975, Eberhard performed Kurt Schwitters’s Ursonate over a hundred times (though he did not, as was incorrectly stated in an obituary that appeared in a Berlin newspaper [6], give the premiere). In addition to his work as a musician and vocal performer, Eberhard mastered the art of designing intelligently thought-through concert programs—“Positions of the modern” (1988), “Stations of musical modernism” (1989), “Stefan Wolpe and the musical avant-garde” (1990), “With other ears” (1991), “The art of the series” (1993) [7], and most recently, in 2012, together with Erhard Grosskopf, the series “On the discipline of anarchy” at the Akademie der Künste, in which he was at last able to realize his long-cherished plan to present John Cage as a composer of traditionally-notated music.
