A hip little piece by my friend Jordan Walsh.
A brief description from the composer:
B_MINUS is an audible representation of the learning process. The percussionist plays a constant stream of notes, slowly adding more complex patterns as the piece progresses. The electronics are pushed forward by the effort of the player: they start out slowly, gaining speed and density until they eventually line up with the percussionist.
