Only the Sound Remains is a chamber opera by Kaija Sariaho based on two Noh plays translated by Ernest Fenellosa and Ezra Pound. The piece was premiered in Amsterdam in 2016 by Dutch National Opera, where it was recorded. It’s a co-pro with Teatro Real, Finnish National Opera and the COC so Toronto audiences will likely get a look at it eventually. Which is good because it’s really hard to figure out much of it from the video recording. As he so often does, peter Sellars directs for both stage and camera and while I like his stage work here I find his video direction quite annoying, especially in the first piece.
