This weekend in Washington:

I reviewed WNO’s iteration of one of Domingo’s latest vehicles, Gluck’s “Iphigenie en Tauride,” and he pulled it off yet again. Not bad for a 70-year-old man. (Since people have been asking: Giuseppe Taddei made his Met debut as Falstaff at 69; Giovanni Martinelli sang the Emperor in Turandot at 82, and Carlo Bergonzi tried, and sadly failed, to tackle Otello in concert at 75. Does anyone have other examples of venerable male singers who have been able to deliver the goods until late in life?)

Marin Alsop and the BSO took on “Das Lied von der Erde,” with calculation and, after all, some effect, in my view.

Robert Battey shook his head over the antics of the pianist Denis Matsuev at Strathmore.

The Bach Sinfonia failed quite to convince Charles T. Downey with its multimedia, video-accompanied “Four Seasons.”

The omniverous violinist Colin Jacobsen showed a few more facets in a program with Bruce Levingston at the Library of Congress; Joan Reinthaler was impressed.

Earlier, Reinthaler reported, the Musicians from Marlboro had a shakier outing at the Freer that improved as it went along.

And a major concert I was sorry to miss: Joe Banno saw and heard Pierre-Laurent Aimard work his magic on Liszt thanks to WPAS.

Here, for those of us who missed him live, is Aimard talking about his approach to piano, and particularly to Schoenberg’s piano concerto.

What did you think of the weekend’s concerts? (Reviews of Sunday’s concerts will follow tomorrow.)
