Klaviermusik
Klaviermusik (English: Piano Music) is the sixth release of Einstürzende Neubauten's Musterhaus project, a series of highly experimental CD releases that were only available via an annual subscription through their website or from shows during their 25th Anniversary Tour. This project was separate from their Neubauten.org Supporter Project, to which it ran concurrent.
The central idea of this Musterhaus release is providing new recordings of both rare and old piano compositions by individual members of the band and entirely new compositions by them, all played on one piano in Ari Benjamin Meyer's apartment.
