In this multimedia performance—presented in association with "Artists in Action," BAM’s Visual Art Initiative—Kerry James Marshall employed the Doppler Effect to break down chance discovery through poetry, narration, music, and film. According to the Doppler Effect, with any wave-type movement, the pitch of a sound or color of a light (frequency) is determined by the speed at which the wave passes the viewer. This event featured Kerry James Marshall as director, designer, and videographer; Cheryl Lynn Bruce as narrator; Alva Rogers on vocals; John Sherman on accordion; Fred Ho as baritone saxophonist; and Elizabeth Alexander as poet/writer.
