The tried and proven order of the traditional symphonic concert program dictates a short introductory piece, followed by a well-known concerto featuring a well-known soloist; then, after interval, a symphony to showcase both the orchestra’s and the conductor’s abilities. This palatable menu was, however, presented with a twist at this week’s concerts of the Sydney Symphony Orchestra. The invited conductor for the series, Thomas Søndergård, clearly made it his business to present the music of Jean Sibelius with the utmost care, right from the first note.
