Het Rattenkasteel (opera)

[1] The work was performed by the theatre group "De Sluipende Armoede" and actors such as Marc van Malderen, Guido Naessens, Lieven Deroo, Martien De Craene, and others.

[1] The idea to adapt an album of The Adventures of Nero for opera came about when Sierens and De Smet were having a drink.

The work was performed in an avant-garde style, complete with percussion and diamond blades as musical accompaniment.

The general public enjoyed it, but professional critics disliked it and compared it to a school play.

[5] Marc Sleen referenced the opera in The Adventures of Nero story "Het Achtste Wereldwonder" ("The Eighth Wonder of the World") (1995–1996), where in strip 91 mention is made of a gang who call themselves "De Sluipende Armoede", which was the name of Sierens' theatre company.
