Of the vast repertoire of works for solo piano and orchestra, Tchaikovsky’s First Piano Concerto is one that many listeners would pick to hear first. Macedonian pianist Simon Trpčeski is soloist for the well-loved concerto that was debuted in 1875 in Boston for an American audience. The all-Russian program continues with Venezuelan conductor Ilyich Rivas leading the orchestra in Rachmaninoff’s passionate Symphony No. 2, which features one of the most ravishing melodies Rachmaninoff ever composed.
