I can affirm most wholeheartedly that Beethoven’s Missa Solemnis absolutely succeeds outdoors on a balmy June evening, as proved last night by the Chicago Grant Park festival and its capable conductor, Carlos Kalmar. I’m too lazy to look it up, but was it not so long ago that outdoors summer festivals avoided pieces like the Missa? In any case, any and all times and places are right for this engrossing and highly accessible work.
