The Philadelphia Inquirer calls young violinist Benjamin Beilman “monstrously talented.” He brings an engaging stage presence and effortless technique to the SLSO for the first time with Mozart’s playful Fifth Violin Concerto. Cristian Măcelaru, a St. Louis favorite, brings a study in contrasts. We feel the heat in Hannah Eisendle’s virtuosic heliosis, then warm ourselves by the autumnal glow and golden hue of Brahms’ richly pastoral Second Symphony.
