Fourganic (2008), for percussion quartet, roughly divides into three sections: the first section is non-pitched, and is characterized by steady growth, a conservative use of material, and a pervasive pulse. The second section, which features pitched instruments, is more nebulous in character, incorporating both proportional notation and improvisation. The third and final section aims to combine these two contrasting events into a coherent, yet transfigured whole.
