For tomorrow afternoon’s chat at La Casa della Cieca, your doyenne offers an unusual double blast from the past.

The suggested listening for this chat will be an on-demand rebroadcast of a series of episodes of “Unnatural Acts of Opera” dedicated to the December 7, 1975 performance of Verdi’s Macbeth from La Scala, featuring the following personnel:

Macbeth – Piero Cappuccilli; Lady Macbeth – Shirley Verrett; Banco – Nicolai Ghiaurov; Macduff – Franco Tagliavini; Malcolm – Nicola Martinucci.Orchestra e Coro del Teatro alla Scala. Conductor: Claudio Abbado.

This week’s chat is a little different, cher public. Instead of listening to a live broadcast internet radio, the interested listenr may simply click the “play” button on the player on the La Casa della Cieca page at 1:00 PM EDT and we’ll all be in synch. (If you arrive late, simply ask someone in the chat how far the stream has advanced, and jump to that point in the stream if you like.)
