‘Pictures at an Exhibition,” close up with the BPO Stefan Sanders is conducting the BPO’s “Know the Score.” Tweet By Mary Kunz Goldman on Wednesday, February 25, 2015 2:41 PM, updated: February 25, 2015 at 2:57 pm ADVERTISEMENT Culminating in the great, clanging chords of “The Great Gates of Kiev,” Moussorgsky’s “Pictures at an Exhibition” fires the imagination from its first notes. Moussorgsky was, in turn, inspired by the artwork of Russian artist and architect Viktor Hartmann, a friend of his. That friendship will be in the spotlight Friday evening, when the Buffalo Philharmonic Orchestra’s “Know the Score” series explores the links between the music and the images. Like the music itself, the concert is a kind of collaboration. The Albright-Knox Art Gallery will be showing treasures from its collection as the orchestra plays the music in arrangements by Stokowski and, most famously, Ravel. A brief excerpt from Ravel’s “Valses nobles et sentimentales” will be played by pianist Claudia Hoca, who was injured in a car accident in the summer of 2013 but is now happy to be back on the musical scene. Reached on the phone by The News, Hoca said how much the community’s support has meant to her during her recovery. “I was floored,” she said, “and tremendously grateful.” She also said, laughing, “Every day is a gift.” The concert is at 7 p.m. Friday in Kleinhans Music Hall. Stefan Sanders, the BPO’s new associate conductor, will be on the podium. “Know the Score” concerts are about an hour long, and are followed by parties where concertgoers and musicians may meet and mingle. Tickets are $34.50, students $15.50. For info, call 885-5000.
