Unquestionable masterpieces: the New World Symphony – inspired by American popular music and melodies from the longed-for Bohemia, the Third Concerto by Prokofiev which is spectacular and of great difficulty, and Darkness Visible by Benet Casablancas, resident composer of L'Auditori and the OBC. Although composers write dozens and dozens of works, there is always one that stands out above the rest. In the case of Dvorák, there is no doubt: his most popular piece is the New World Symphony, written and premiered in the United States. For Prokofiev, of the five piano concertos that he composed, the third is the most played worldwide: a work of great brilliance and virtuosity. And in the case of Benet Casablancas, his masterpiece is a work premiered in 2012 by the London Philharmonic and recorded by the National Orchestra of Spain.
