Any 
          performance of a Mahler symphony is an occasion, 
          but this one had something extra. Before it 
          even began, a representative of NARAS delivered 
          the orchestra's Grammy Award for best classical 
          recording, announced last month, honoring 
          its 2-CD set with music director Michael Tilson 
          Thomas of Mahler’s Third coupled with 
          Kindertotenlieder. Then, after a short 
          first half of forgettable Beethoven marches 
          and a Cherubini overture, Tilson Thomas and 
          the orchestra delivered something unforgettable 
          of their own, a Mahler Fifth bristling with 
          brilliant solo turns and glorious ensembles 
          held together by an interpreter who never 
          seems to take a false step with Mahler these 
          days.
        
        Conducting 
          without a score, Tilson Thomas led a traversal 
          that was not so much a sustained journey than 
          a celebration of all the dead ends, wrong 
          turns and unexpected blazes of sunlight in 
          Mahler's score. In the Fifth, completed 
          in 1904 and revised finally in 1907, the composer 
          of four song-saturated symphonies was searching 
          for a new direction. He found it, edging closer 
          to a more dissonant harmonic language, incorporating 
          a great deal more polyphony and, despite its 
          more traditional, symmetrical form, the music 
          goes skidding off into ever more unexpected 
          byways.
        
        In 
          a letter to his wife, Alma, Gustav Mahler 
          wrote, ""Heavens, what is the public 
          to make of this chaos in which new worlds 
          are forever being engendered, only to crumble 
          into ruin the next moment? What are they to 
          say to this primeval music, this foaming, 
          roaring, raging sea of sound, to these dancing 
          stars, to these breathtaking, iridescent, 
          and flashing breakers?"
        
        Right 
          from the opening measures, Mahler sets the 
          tone. An extended solo fanfare, played here 
          with barely-contained nervous energy by principal 
          trumpet Glenn Fischtal, leads to an orchestral 
          explosion that rapidly collapses onto itself, 
          leading to the statement of the first, highly 
          lyrical theme by hushed violins. It was an 
          omen of great things to come that the crash 
          of the orchestra rocked me back into my seat, 
          and the violins played that first theme with 
          such spectral, virtually vibrato-free sound 
          that they had me leaning forward again.
        
        That 
          kind of attention to detail showed itself 
          repeatedly throughout this performance. Especially 
          intriguing was the astonishing array of timbres 
          coming from the violin section. At one point, 
          the violins sustain a note that, a few seconds 
          later, the horns would pick up and extend 
          into a long, arching melody. The violins actually 
          shaded their sound to something almost metallic, 
          foreshadowing the horns' entry. At another 
          point, with the strings playing pizzicato, 
          associate principal bassoon Steven Dibner 
          entered with a counter melody that had the 
          same quick attack-and-release sound as the 
          plucked strings. Musicians often do this. 
          Dibner got the sound so right, he sounded 
          like a cello.
        
        The 
          net effort of all this not only created interesting 
          effects, but also a palette of sound that 
          served to glue the music together. With so 
          many different ideas coming and going in the 
          score, it can easily seem episodic and unrelated. 
          These timbre mirrors were part of the solution. 
          Another part was Tilson Thomas' approach to 
          tempo relationships. The pulse ebbed and flowed, 
          but always came to rest with a clear relationship 
          with what came before and what was coming 
          afterwards. Phrasing always had shape.
        
        The 
          results were riveting, especially in the sprawling 
          scherzo that is the centerpiece of the five-movement 
          work. The horn section, led by principal Robert 
          Ward, distinguished itself, not only playing 
          with accuracy but shaping their sound to make 
          it round and mellow one moment, nasty and 
          blaring the next. The famous Adagietto, which 
          followed, taken at not quite as slow a pace 
          as often heard, still created a sensation 
          of hovering quietly. Again, the strings went 
          for a hollow sound in the quieter sections, 
          only introducing vibrato in those few measures 
          when the volume increased to forte, a courageous 
          and striking effect.
        
        After 
          all this seriousness and exploration, the 
          finale refuses to take itself seriously. Several 
          times it reaches for a climax, only to brush 
          it aside in favor of music that seems to giggle 
          behind its hand. The most obvious example 
          is at the very end. Having spent more than 
          an hour moving away from the complex key of 
          C-sharp minor, Mahler finally reaches the 
          final pages in the sunny, open key of D major. 
          Even as the brass chorale from the second 
          movement returns in a gesture of triumph, 
          intoned brilliantly by massed trumpets, trombones, 
          tuba and horns, the final measures intrude 
          with a rapid scurrying and a final whump! 
          that always reminds me of door slamming. The 
          orchestra nailed this finish with such vivid 
          execution half the audience was out of its 
          seats almost on the rebound.
        
        Audio 
          evidence of this turbo-charged performance 
          can be heard the week of March 15 on radio 
          stations, including those heard on the internet, 
          that carry the San Francisco Symphony broadcasts.
