Among all the singing solidity, Plácido Domingo, standing in as Siegmund in Die Walküre, was the standout. His tone rang with a ping, his phrases always went somewhere and he never tired (despite an apparent cough). And with what must have been little or no rehearsal, he managed his maneuvers smoothly enough.
Placido Domingo has dropped most of the roles from the Italian and French repertory that made him famous. But here, in the baritonial tenor role of Siegmund, he sounds very much like he did more than two decades ago when he first took on Wagner.
The presence of Domingo seemed to captivate the company in "Valkyrie," which was stronger in every way than "Rhinegold." ... Domingo was in outstanding form, his voice genuinely heroic, a rapt actor looking impossibly youthful.
