For an instrument with such rich expressive powers, the cello has long suffered from a shortage of great concertos. Leave it to John Williams, the composer best known for his popular, emotionally charged scores to Star Wars, ET, and many other blockbuster movies, to ride to the rescue with a new Cello Concerto -- an intense, expressive, and rhythmically vital offering tailor-made for Yo-Yo Ma's dexterous touch. Like the composer's Violin Concerto, this one is imbued with impressionistic textures and colors, but there's also a hard-driving, modern edge. Call it 21st-century Ravel. Williams wrote the concerto with Ma in mind, and it's a test of even Ma's formidable technique. It also boasts powerful orchestral writing, especially for the percussion and brass. Three other premieres are included on the album as well. The Elegy for Cello and Orchestra is a lyrical and atmospheric tone poem, with shades of Fauré at every turn of phrase. The expressionistic Three Pieces for Solo Cello, though, seem more akin to Benjamin Britten's solo cello suites in their abstract, concentrated intensity. Heartwood is another tender and sensitive reverie. It gradually builds in strength but ends as it began, with a whisper of tranquil serenity. Ma's virtuosity is dazzling, and his engagement with the music is typically deep. He makes clear that Williams's music isn't just for the movies; indeed, with his new concerto, Williams has done the cello a great service.
