“Hammerklavier” is a full-length cycle in which the composer sends the listener on a journey, a journey into the unknown; this journey presents itself as an act of unleashing, taking Eggert on a departure from the traditions of our planet. The title does not refer to a concert piano, nor to Beethoven’s Hammerklavier Sonata, but to a specific manner of playing: the pianist does not only have to touch the keys, but to be a “performer” in the wider sense. Pieces I-XI have already appeared in two volumes (ED 8622 and ED 9137) and on a recording under WERGO (WER 6611-2) played by the composer.
