In the sublime slow movement, the pensive Adagietto, Mr. van Zweden did not allow a trace of sentimentality. The tempo was slow, but flowing; the phrasing sensitive, yet shapely. But I wanted more depth and sadness. In the performances that have most moved me, there was a sense that this music could hardly bear to expose itself. There was little of that quality here.
With these performances of the Glass concerto, featuring the splendid pianists Katia and Marielle Labèque as soloists, Mr. van Zweden has filled a gaping hole in the Philharmonic’s history. Overlooking Mr. Glass’s work had to have been a deliberate choice by a succession of music directors, because, love him or hate him, he has been an influential figure in contemporary classical music for some 40 years.
And this 27-minute concerto in three movements, which had its premiere in 2015 with the Los Angeles Philharmonic, is inventive and unusual. The orchestra starts off abuzz with rippling, subdued riffs. Almost immediately the pianos, backed by various instruments, play a slippery theme in chords that dip and rise almost step by step.

Mr. Glass ends his concerto with a wistful slow movement. Recurring figures in triplets hover in the pianos, while a sighing, spare melody floats above in bare octaves.
The piano parts, though not showy, are detailed and…
