This concert presents three transporting works by composers of different nationalities and sensibilities. Arvo Pärt’s Summa is a brief but hypnotic work by one of the most beloved living composers. Tchaikovsky’s Violin Concerto, the first of the classical Russian violin concertos, is the forerunner of concertos by Prokofiev, Shostakovich, and others. It is a brilliant virtuoso showpiece crammed with some of Tchaikovsky’s most beguiling melodies. Brahms’s Second Symphony is the most mellow and spontaneous of his four yet written with his characteristic formal rigor. The orchestration has a crystalline transparency we normally don’t associate with Brahms, and the brassy fourth movement is the composer’s most viscerally exciting finale.
