Scored for singers and electronics, Rainbow Passage is a multimedia concert based on a popular diagnostic text by speech scientist Grant Fairbanks, containing every sound of the English language. These sounds are first intoned literally, then fragmented much as the sunlight strikes raindrops, and rewoven into a vocal tapestry that communicates beyond language, simultaneously evoking the myth and science of rainbows. Rainbow Passage gathers a vivid cross-section of Portland’s musicians, including alt-Classical vocal quartet The Julians, the cosmic electronics and bass clarinet duo of Matt Carlson and Jonathan Sielaff (Golden Retriever), and celebrated songsmith Holcombe Waller. Artist Brock Monroe creates a video and light installation that bathes the performers and audience in prismatic color.
