Tonight, 8 July, at 8pm CET (that's 7pm UK), the Bavarian State Opera will stream Fidelio live from Munich on their website.
Calixto Bieito's production, which premiered in December 2010, features Anja Kampe as Leonore and Jonas Kaufmann as Florestan. Adam Fischer conducts and the event will be introduced by TV presenter Thomas Gottschalk, who is like the Jonathan Ross of Germany only without the obscene phone calls.
I won't be turning my laptop on - because I'll be live from Munich too. (May tweet, may not.)
