Joe Banno attended what was evidently a stunning concert by Yefim Bronfman on Friday night.

Charles T. Downey had a busy weekend, first covering the Jerusalem String Quartet at Wolf Trap, and then checking out the young pianist Benjamin Grosvenor (who just released a new CD with Decca).

In Baltimore, Samantha Buker heard and saw the Baltimore Symphony Orchestra perform Einhorn’s Voices of Light, the Joan of Arc oratorio.

And on Sunday, Joan Reinthaler heard the Nordwest Deutsche Philharmonie, with the cellist Amit Peled, at George Mason University.
