"Fields" performed in Barcelona's "Festival Mixtur"

"Fields" takes place with two percussionists separated at a linear distance of 150 yards. There is a microphone placed at each performer. Four additional microphones partition the duo, whose distances are structured distinctly upon ratios of the harmonic series. These distances are sought after, as the piece is written specifically around these spacial arrangements, their spacial frequencies and their relationship to the speed of sound. 

Performed by Mark Knoop and Serge Vuille, program and performer details here
