I mean't a full production with complete visuals, I know that they've all been performed (and apparently will all be performed again in two years).
Some/most of the stuff is technically near impossible to stage perfectly, so they have to take other routes to perform it. For instance Welt-Parliament or Evas Zauber.

Yes, these were all "full production[s] with complete visuals" - Welt-Parlament, which is a cappella was not only done in Stuttgart in '96, but was included in the opera premiere of Mittwoch in 2012 and Evas Zauber was premiered in '86 and performed in Milan in '88 as part of Montag.

Well what I mean is, for example: there's that intergalactic meeting between the world leaders, which we're supposed to be immersed in (well the music is incredible) but we have a bunch of people on stilts in a warehouse, not really trying to visually create what it's trying to convey.

Perhaps it's just me but I don't feel as though Karlheinz was intending to create something THAT visually abstract, with his highly ambitious and sort of esoteric cosmic opera cycle.

What do you think? :o:
