The MSO’s Water Festival continues with Rameau’s Suite from Naïs, his French Baroque opera depicting the sea god Neptune’s love story with the eponymous water nymph. The operatic nature persists with the virtuosic Concerto for Double Bass, performed by MSO’s own Principal Bass Jon McCullough-Benner. Handel’s jubilant Water Music, originally written for performance on the River Thames for King George I, fills Allen-Bradley Hall with gorgeous flowing melody.
