Making their BSO subscription debuts, two rising stars showcase their talents. YouTube sensation Valentina Lisitsa brings passion and drama to Mozart’s D-minor piano concerto. Joshua Weilerstein leads the BSO in Mendelssohn’s evocative musical reminiscence of the Scottish highlands and also Prospero’s Rooms, channeling the gothic energy of Edgar Allen Poe’s “Masque of the Red Death” composed by Baltimore’s own Christopher Rouse.
