riverrun was premiered by students in the University of South Florida percussion studio in the spring of 2013. This work features various types of instruments from the different families of percussion; metal, wood, skin, and found percussion/other. Each performer has five different instruments from one of the families. The rhythmic material is derived from the Morse code realizations of four randomly selected letters MSHL. The resulting rhythm is presented in augmented and diminished forms throughout the piece.
During the course of this work, different periodicities are utilized simultaneously to create a sense of chaos that is juxtaposed against brief moments of clarity. Aside from the highly rhythmic atmosphere, the overall timbre constantly shifts between different combinations of percussion instruments.
