Hans Werner Henze, Fünf neapolitanische Lieder. Hermann Prey, NDR-Sinfonieorchester, Hans Schmidt-Isserstedt, conductor, recorded Hamburg, Musikhalle, September 19 1956, the year of composition. I am not aware of this ever having been released commercially. Prey sang the songs at the London Proms on September 11 1962.
Dietrich Fischer-Dieskau had given the premiere in Frankfurt on May 26 with the Sinfonieorchester des Hessischen Rundfunks under Otto Matzerath. A recording of that occasion may be available here. The radio station had commissioned the work.
In the same year “Fidi” recorded it for Deutsche Grammophon with members of the Berlin Philharmonic under Richard Kraus.
The songs use anonymous seventeenth-century texts. There are some Stravinskyan chords. The titles are Aggio saputo ca la morte vene, A l’acqua de li ffuntanelle, Amaie ’na nenne pe’ tridece mise, Amaie ’nu ninno cu’ sudore e stiente and Arbero piccerillo, te chiantaie. Walton admired them. They are dedicated to Ingeborg Bachmann.
