"People sometimes complain that Wagner operas are too long, that they get stiff and sore about 10.30 because they have rushed in to hear one of his works straight from work and are not properly prepared for listening to his music. The audience, as much as the artists, must be prepared for a performance."
(Benjamin Britten to Alan Blyth, Gramophone)

"People will enjoy the Ring and Parsifal until, one fine day, they will get tired of being pitched around on a sea of endless melody and led around by stereotyped leitmotives." (Eduard Hanslick, 1882)

"I was bowled over. It was the year after Wieland Wagner had died; to be able to see his productions was a total knock-out. These bare stagings, where everything was done with lighting. The light changed with the music, and the shadows and patterns seemed as archetypal as the music itself. Nobody had done that on the stage before. I thought it was extraordinary and wonderful."
(Patrick Carnegy to The Guardian)
