The great ensemble inaugurates the new season with a juxtaposition of some of the chief conductor’s chief priorities: the Symphony No. 4 in E minor, op. 98, of Brahms, because Brahms belongs to the orchestra’s historic core repertoire; and Schoenberg’s Verklärte Nacht (Transfigured Night), because of Petrenko’s dedication to the aesthetic upheaval at the dawn of the 20th century. Mind you, while the advanced harmonies of the Schoenberg baffled many at the premiere in 1902, this breakthrough work goes down easy now. Can the maestro restore the sense of unease and dislocation? And is that his agenda? We shall hear, and we shall see. —M.G.
