Sunday afternoon’s program at Tanglewood opened with the American premiere of Fazıl Say’s 2020 concerto for piano four-hands and orchestra, Anka kuşu (Phoenix), featuring Lucas and Arthur Jussen, who had also performed the world premiere in Munich this past January. Unlike many contemporary composers, Say employs a small orchestra and little in the way of exotic percussion. His concerto is atmospheric, beginning subdued and dark with an hypnotic, chant-like passage. A percussive volley from the piano triggers a turbulent, syncopated episode. As the piece progresses, the brother playing the left hand part rises from the bench to pluck the piano’s strings or to cross his hands over to the other end of the keyboard. At times the pianists contend, at others their parts interweave or coalesce. The strings punctuate the syncopation playing col legno. After a rhapsodic interlude, a more jazzy syncopated passage begins and drives the concerto to a brilliant conclusion. In typical Tanglewood fashion, a clutch of local songbirds had added an unexpected touch of Charles Ives to Say’s composition.
The Jussens played as one, blazing along the keyboard with precision and breathtaking dynamism. Their energy and commitment carried over to the orchestra and drove the concerto to a cathartic conclusion, with the audience in the Shed rising to its feet with a roar, continually recalling them and Nelsons to the stage.
