Bug Snatches Spider consists of three movements. The first movement, Version I, features long linear developments and densely contrapuntal textures that thin out more and more towards the end of the movement. It ends with the singular sound of a high violin cut off by a pop. The second movement, Version II, surges through sections that are shorter and less intricate than those of the first movement, towards five fortissimo beats. Some of these sections have aleatoric structures, others are built as instrumental choirs. The last movement, Aggregate, is for a lone piano. It is nothing but a single long sequence serenely descending to the lower end of the keyboard. The material of this movement contains the essence of the material used to compose the previous two movements.
