Last week was a hellishly busy one around here (four concerts, three interview features, a handful of news stories) so I skipped Friday's Berkeley recital by Krystian Zimerman despite my unbridled awe at his artistry. Big mistake. Not only does it turn out that this was his final U.S. tour for the foreseeable future (who knew?) but evidently he had some weighty stuff on his mind, to judge from this report of Sunday's recital in L.A. Nothing so overtly dramatic happened up here — I checked — but it would've been good to witness that kind of passion in action.
