AS A performer, Scottish harpist Savourna Stevenson crosses many musical boundaries. As a composer, that eclecticism informs a delicious little "musical adventure" called Misterstourworm and the Kelpie's Gift, which she claims is the first such narrated piece since Prokefiev's Peter and the Wolf. That's debatable, but the bottom line is this: it is a delightful work, narrated here by actor Billy Boyd, sung by the National Youth Choir of Scotland Edinburgh branch and the RSNO Junior Chorus, with the Scottish Opera Orchestra under Christopher Bell's direction. Add to that some other songs by Stevenson and a colourfully illustrated booklet, and the package is just the ticket for young children who like a good tale well told....Kenneth Walton..
