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.

Two compositions from Berlin-based Australian composer-instrumentalist Jon Heilbron scored for two double basses and two hardanger fiddles--violins with extra sympahetic strings-- in his two part "Puma Court", a slowly-evolving work that develops uniquely rich acoustic environments of interacting harmonies & timbres, punctuated with subtle percussive elements.
