Two hauntingly beautiful works in microtonal composer and violist Catherine Lamb's "Prisma Interius" series, the first a duo with violinist Johnny Change and Xavier Lopez on the "secondary rainbow synthesizer", which channels the sound outside of the performance space as a generator of ambient sound; then a sextet of strings and winds with two secondary rainbow synthesizers.
