Music@Menlo’s second week transports listeners into Mendelssohn’s fantastical reimagination of A Midsummer Night’s Dream. Concert Program III, given its first performance on Monday evening to a sold-out Stent Family Hall audience, surrounds Mendelssohn’s incidental music to Shakespeare’s classic play with a colorful tapestry of works by Schumann, Spohr, and György Ligeti. Listeners get two more chances to hear this enchanting program, on Tuesday and Wednesday evenings (8:00 p.m., Stent Family Hall [Tue], St. Mark’s Episcopal Church [Wed]). On the accompanying Prelude Performances, the International Program students complement these offerings with three stalwart Romantic voices: Schumann, Dvořák, and Brahms. The music of Brahms and Dvořák also takes centerstage at Tuesday’s master class, led by pianist Jeffrey Kahane (12:00 p.m., Stent Family Hall).
