As reported earlier, La Scala closed its doors today due to a salary strike, cancelling tonight's Barenboim-conducted Verdi Requiem with Frittoli, Gubanova, Alvarez & Youn, in memory of Toscanini's 50th year of passing.
You can read the announcement on in Italian on the La Scala website, which was whittled-down to like a paltry 3 sentences in English.
However, arriving in person to the theater, no pretense was made at informing the non-Italian-speaking public what is going on, as the only effort to advertise the strike was a small text block, Italian-language only.
^^^^ here's how it looked from a bit futher away.
