Originally written as a set of piano pieces, Mussorgsky’s splendid Pictures at an Exhibition translates the artistry of the composer’s friend Victor Hartmann into unforgettable music. Peter Breiner’s new orchestration creates a showpiece for our times, achieving contemporary sounds through unusual instrumental combinations, right up to a spectacular Great Gate of Kiev performed by 104 musicians. Mussorgsky’s remarkable song cycles contrast encounters with death against the often uneasy world of children in The Nursery.
