JAMES MACMILLAN, Le Tombeau de Georges Rouault. Boosey & Hawkes 13879. This work was commissioned for Symphony Hall, Birmingham, England, where it was premiered in 2004 by Thomas Trotter. There are at least half-a-dozen musical ideas, of which one, an initial countersubject marked "brash, clowning," becomes paramount within the course of development. The single-movement ternary formal scheme is well-calculated, but there is too much stopping and starting, and some of the writing is far from idiomatic to the organ. Despite the large design, the affective scope is overly economical, and does not traverse as much ground as one might expect in a fifteen-minute concert piece.
