This engaging disc of Mendelssohn’s overtures forms the final volume of Edward Gardner and the City of Birmingham Symphony Orchestra’s survey of the composer’s major orchestral works. It’s carefully programmed to place the familiar alongside the less well known, the rarities, in this instance, including the early Trumpet Overture, composed in 1826 just before A Midsummer Night’s Dream (the late opus number is deceptive), the Overture to St Paul, seldom heard away from an oratorio that is itself performed infrequently, and the once popular Athalie, which nowadays we don’t perhaps hear as often as we might.
