The jockey is the most intriguing of athletes. Modest of stature and physique, he must read and ride horses weighing ten times or more than he does, channel their power, know when to hold them back and when to give them free rein to run. The best become one with their ride. Perhaps it is no accident, then, that the slight and self-effacing Daniil Trifonov not only looks like a professional rider but approaches that Man o’ War of piano concertos, Rachmaninov’s Third, exactly like one. He began Friday afternoon’s performance with Andris Nelsons and the Boston Symphony at a canter, sitting still and upright on the bench. Only his fingers moved. The notes were lucent, the tenor hushed and musing. As the music became more animated, so did he, leaning in and giving the movement its head. In more emphatic passages, like the chordal barrage of Rachmaninov’s dark, first version of the cadenza, he bounced up and down like a rider posting for a show jump, momentarily throwing the weight of his entire body behind his hands. The cadenza’s thundering intensity almost overwhelmed the first movement and clean articulation of melody and rhythm sometimes fell prey to blinding speed, but, for the most part, Trifonov aptly paced himself through the soulful lyricism of the second movement to a final burst of prancing speed in the chimerical third. Nelsons and the orchestra followed his lead, their own exuberance occasionally swamping the piano.
With its virtuosity of simplicity and chamber music textures, the Fifteenth Symphony of Shostakovich couldn’t have provided a greater contrast to Rachmaninov’s rainforest of notes and lush melody. Written in a month in 1971 and mostly in the hospital where the composer was being treated for a cascade of health issues, his final symphony describes a cradle-to-grave arc and is flecked with quotes from Rossini, Wagner, various others, and Shostakovich himself. He originally subtitled the first movement “The Toyshop” and it does convey the sense of a shop overrun with children exuberantly playing toy wind and percussion instruments and winding up various things and letting them loose. Lively and bright, the movement is anchored by the opening flute motif which passes to other instruments, then contends, and intertwines with a recurring quote from the concluding galop of the William Tell Overture.
