Gloria Coates (b. 1938) is of a modernist generation for whom music is a vehicle for dark, disturbing emotions, for whom the range of musical sounds must be greatly expanded to blast through audience complacency and address the special horrors of our time. At the same time, she is capable, as few members of her generation are, of limiting her materials and welding a work into a single gesture. She realizes, as most serialist and expressionist composers have not realized, how much more intense a piece of music can become when it is narrowly focused, when it does not flutter around to every possible technique, but hammers away within well-defined limits.
