Mauricio Kagel has long since become a classic as a composer. Reason enough to look at him through Kagel's glasses. The Ensemble Megaphon has, together with the composer and interaction artist Bernhard Kingwho was one of Kagel's last students, developed a framework composition in a dialogue process that forms the "red thread" of the programme and throws anecdotal spotlights on Kagel's life and work. The rest is improvisation ranging from "quite close to the original" to complete "decaging" that runs counter to all the master's intentions.
