Trumpet and organ - and yet conceivably removed from the usual of this popular instrumentation: that is "O Mensch, gib Acht!" - is not only an eye-catcher but also a programme, when the world-class trumpeter Reinhold Friedrich and the Essen Cathedral organist Sebastian Küchler-Blessing place contemporary works, which were written as a reaction to the horrors of the Third Reich, in dialogue with arrangements of Romantic works: in addition to the titular slow movement from Mahler's Third, "Kol Nidrei" by Max Bruch and Brahms' "O Tod, wie bitter bist Du" are heard. Zsigmond Szathmáry, who was highly esteemed by György Ligeti, wrote an "...ad memoriam..." about the Holocaust Memorial in Berlin especially for this production. The brother and sister duo Kristina Schoch (recorder) and Andre Schoch (trumpet player with the Berlin Philharmonic Orchestra) also participated in other works, such as four epigrams based on Hebrew songs for recorder and organ pedal by Otfried Büsing from Freiburg. Recorded on the Rieger organ in Essen Cathedral, which was rebuilt after the destruction of the war, war is raging on European soil at the same time. Gib Acht!" has ever been more topical.
