A welcome encore performance for Cincinnati favorite Hélène Grimaud, who played Brahms’ turbulent, dramatic and entirely captivating First Concerto to glowing reviews when she last performed here in 2007. Music Director Louis Langrée completes the program with Beethoven’s wittiest, most good-natured symphony, which the composer wrote during one of the most difficult personal periods of his life—while he was involved in a passionate, but doomed, love affair, the affair with the mysterious woman known as his Immortal Beloved.
