Chad Heiny’s brilliant piece Bad Juju juxtaposes deep African grooves played on traditional instruments and dissonant harmonic material played on three marimbas to create a feeling of uneasy suspense throughout the work. Although not a story per se, the piece conjures images of voodooism, bewitchment, and impending doom, sure to raise a few hackles from the listener. There is also plenty of technical demand to satisfy the appetites of experienced players.
