Rossini Mose in Egitto (Moses in Egypt) from the WNO now on BBC Radio 3. This broadcast was made during the run in Cardiff. Sounds pretty good. Please read Robert Hugill's review HERE in Opera Today. I quite enjoyed it, though it sounded more like Handel to me than Rossini. That's no big deal and it's illuminating to listen from a different angle. Possibly I've been spending too much time listening to the Pesaro production (conducted by Roberto Abbado, nephew of Claudio) reviewed HERE by Michael Milenski in Opera Today. WNO isn't going to compete with Pesaro, so I don't at all have a problem enjoying some of the best British-based singers in WNO Mose in Egitto.
Incidentally, one of the interesting things about Rossini's Guillaume Tell is how "German" it sounds, as if Rossini's been imbibing Carl Maria von Weber.
