This week’s Pipedreams program takes on the challenge of evoking vivid visual images - and with our ears we’ll view a procession in an ancient cathedral, a thunderstorm in the countryside, colorful landscapes in southern France, and an art show at a gallery. Along with works by Mulet, Ermand Bonnal, Eugene Reuchsel, and Lefebure-Wely, we’ll enjoy a complete performance of Mussorgsky’s famous keyboard impressions of paintings by his friend Victor Hartmann - visions of children playing near the Tuileries, the Market at Limoges, the Catacombs, the Ballet of the chicks in their shells and the Great Gate of Kiev. Nine soloists paint the town with organic colors. For more on Pictures at an Exhibition, read Paintings in Sound, by Michael Barone.
