Mike Scott Rohan asked, subjectively,
Why can't we do this with the Ring?
There have been steps in that direction: various productions have, with
varying degrees of success, given us projections, athletic and balletic cast
doubles and extras, atmospheric lighting, the occasional spectacular visual
effect and the like. Even as far back as the Schneider-Siemssen Ring and
the first ENO cycle some elements of the sort were tentatively in place.
But what no one single production has managed so far, I think, is to take
the next creative step and mount a Ring where the visual side is given the
sort of central consideration that the Tempest in your link seems to have
given it; where the look of the show is (almost) the entirety of what the
show is about and all the other elements relate to it. The Valencia Ring
came close, perhaps.
