Amazon.comDespite all the praise heaped on this late work by England's greatest 20th-century composer, it remains a very difficult nut to crack. The best adjective to describe it would have to be "gnarly." The music is dark, dissonant, and only elusively melodic until the transfiguring finale, when sunlight finally bursts through the clouds in the form of a lyrical trumpet tune. It takes real concentration on the listener's part, and although the experience is worth the effort, it's something you have to understand from the beginning. Walton's Concerto is easier on the ear, but also of lighter musical substance. Andrew Lloyd Webber plays both pieces with total conviction and considerable tonal beauty. --David Hurwitz
