Carnegie Hall was the venue, just three weeks before Mariss Jansons’ death in November 2019 at age 76. And this, billed as “His Last Concert,” is a poignant memento of a great conductor. The music itself is tinged with melancholy too. The 4 Symphonic Interludes from his autobiographical opera, Intermezzo, despite their moments of rambunctious good spirits, are moving and deeply personal, especially in a performance as touching as this. And Brahms’ Symphony No. 4, with its note of tragedy, takes on extra gravity given the circumstances of this performance. The slow movement is the highlight, poised and exquisitely played by this great orchestra.
