Nathaniel Bartlett's performances seamlessly meld his five-octave acoustic marimba with electronics, a powerful computer, and an eight-channel cube of loudspeakers. With the audience positioned in the center of the cuboid loudspeaker array, a three-dimensional soundfield can be projected into the audience space, totally immersing the audience in the music. In Bartlett's music, the spatialization and motion of sounds is a central musical parameter.
