The San Francisco Opera reran last weekend Verdi's Attila from 2012. It is a fabulous baritone feast with Furlanetto, Kelsey and Ramey. I'm sorry if you missed it.
The sets all relate to interiors of theaters. You may feel free to make up a reason for this. This version seems to be shortened. A film played in one of the theaters, and this has been omitted. In house one sees everything in full screen, while in a film a full screen is unusual. This diminishes the effect of the theater interiors and increases the importance of the singers. It's much better this way.
Here's my review when I saw it live.
